1.0 Introduction
|
|
|
|
HYTELNET is a hypertext browser that allows a user to gain almost
|
|
instant access to all telnet-accessible sites on the Internet.
|
|
It is written for use on an IBM-compatible personal computer,
|
|
running as a terminate-and-stay-resident program.
|
|
The purpose of this paper is not to explain the history and
|
|
operation of the program (that information can be found in a
|
|
previous article). [1] Rather, this article describes the
|
|
different kinds of Internet resources that a user can connect to
|
|
with the help of the program.
|
|
|
|
2.0 OPAC Access
|
|
|
|
Typically, the program is started from its own subdirectory by
|
|
running HR.EXE. This brings up the START.TXT file (see Figure
|
|
1). [2]

If a user selects the SITES1 file, he or she will be presented
|
|
with a list of countries that have Internet-accessible OPACs
|
|
available for browsing (see Figure 2).

-----------------------------------------------------------------
|
|
|
|
Selecting any of the files will bring up a list of sites within a
|
|
particular country. The user then selects the library to access.
|
|
Each library has its own file, complete with telnet address and
|
|
any special login instructions. Currently, a user can connect to
|
|
about four hundred libraries worldwide, including those subsumed
|
|
under consortia.
|
|
One feature that users find helpful is the ability to view a
|
|
file describing the particular OPAC software in use.
|
|
Also included in the program are lists of sites that use a
|
|
particular software interface. At least twenty-one such
|
|
interfaces are in use: BLCMP, BuCAT, CATS, DOBIS/LIBIS, DRA
|
|
Altas, Dynix, Geac, Geac Advance, GvB, Inlex, INNOPAC, Libertas,
|
|
LS/2000, Multilis, NOTIS, PALS, UNICORN, URICA, UTCAT, VTLS, and
|
|
Z39.58.
|
|
|
|
+ Page 17 +
|
|
|
|
For example, if a user wishes to see which libraries use URICA,
|
|
the file SYS012 would be retrieved (see Figure 3).
|
|
|

-----------------------------------------------------------------
|
|
|
|
It is then a simple matter of moving the cursor to the
|
|
appropriate file and hitting the return key. Figure 4 shows the
|
|
screen that the user sees when he or she chooses the Australian
|
|
National University.

To exit, use the TELNET escape key.
|
|
|
|
E-mail contact is helpdesk@library.anu.edu.au
|
|
-----------------------------------------------------------------
|
|
|
|
The user then simply keys in the telnet instructions and connects
|
|
to the remote site. Currently, the IBM PC version of the program
|
|
does not make automatic connections.

|
3.0 Access to Other Resources
|
|
|
|
Of course, there are other kinds of resources available on the
|
|
Internet besides OPACs. This can be shown by invoking the SITES2
|
|
file from the START.TXT file (see Figure 5).

|
|
|
|
-----------------------------------------------------------------
|
|
|
|
Let's look at these Internet resources in more detail.
|
|
Archie is a program that identifies what Internet archives
|
|
hold a particular software package or text file. A user can then
|
|
retrieve the desired file using anonymous file transfer (FTP).
|
|
There are Archie servers in eight countries.
|
|
Campus-wide information systems typically contain general
|
|
information about a particular university or college. Some of
|
|
these systems run sophisticated software that allows keyword
|
|
searching of appropriate files (e.g., telephone directories).
|
|
There are a number of databases and bibliographies available
|
|
on the network, including the Choice book reviews, the Central
|
|
Statistical Office Macro-Economic Time Series Data, the Global
|
|
Land Information System, and the Meeman Archive (environmental
|
|
journalism). In most cases, the databases are fully searchable.
|
|
|
|
+ Page 19 +
|
|
|
|
Distributed file servers include instructions for connecting
|
|
to the latest breed of Internet services: Gopher, Wide Area
|
|
Information Servers (WAIS), and the World-Wide Web.
|
|
Many electronic versions of public-domain literary works and
|
|
some commercial services are available for searching on the
|
|
Internet (e.g., the complete works of Shakespeare, the Lewis
|
|
Carroll novels, the Oedipus trilogy, and religious texts such as
|
|
the King James Bible and the Koran).
|
|
Free-Net systems are among the most popular sites accessible
|
|
on the Internet. There are currently five Free-Nets available,
|
|
with more to be added shortly. These systems are generally
|
|
operated by volunteers, and they contain a wealth of information
|
|
on almost every topic.
|
|
General bulletin boards include the traditional library
|
|
bulletin boards, plus many FidoNet boards that are now making
|
|
connections to the Internet. Many sites require users to pay a
|
|
fee in order to use their boards, and this information is duly
|
|
noted in HYTELNET.
|
|
Earl Fogel of the University of Saskatchewan's Computing
|
|
Services Department recently adapted HYTELNET so that it can run
|
|
on UNIX/VMS machines and make remote logins for users. To see
|
|
this version in action, telnet to access.usask.ca using VT100
|
|
emulation and login with "hytelnet" in lower case. Many other
|
|
sites have loaded this software and they will be noted in future
|
|
versions of the program.
|
|
Many NASA databases are now fully accessible, including the
|
|
Astronomical Data Center, NASA Science Internet Online Network
|
|
Data, and the Pilot Land Data System.
|
|
Information concerning other networks subsumed under the
|
|
Internet can be found in the files listed in the NET000
|
|
subdirectory (listed as "Network Information Services" in Figure
|
|
5). For example, a user can find files describing the activities
|
|
of networks in Germany, the Netherlands, Sweden, the United
|
|
Kingdom, and the United States. Again, very sophisticated
|
|
software is in place for searching.
|
|
A new subdirectory in Version 6.2 of HYTELNET lists various
|
|
types of directory services, including USENET contributor e-mail
|
|
addresses, white and yellow page telephone directories, and WHOIS
|
|
services.
|
|
Finally, there is a file containing miscellaneous resources
|
|
that have not been classified. These resources include such
|
|
services as flight plan filing systems, ocean information,
|
|
publishers' services, and supercomputer facilities.
|
|
|
|
+ Page 20 +
|
|
|
|
4.0 Other HYTELNET Features
|
|
|
|
Two other files which assist the user in making the most of their
|
|
Internet accounts are GLOSSARY and TELNET. The former lists
|
|
terms that a user will encounter during network travel, while the
|
|
later gives tips and tricks for using the telnet program.
|
|
|
|
5.0 Where to Find HYTELNET
|
|
|
|
Version 6.2 of the program is available via anonymous FTP. To
|
|
FTP the program:
|
|
|
|
(1) At your system prompt, enter: ftp access.usask.ca.
|
|
|
|
(2) At the user prompt, enter: anonymous.
|
|
|
|
(3) At the password prompt, enter: your e-mail address.
|
|
|
|
(4) At the command prompt, enter: binary
|
|
|
|
(5) At the command prompt, enter: cd pub/hytelnet/pc.
|
|
|
|
(6) At the command prompt, enter: get hyteln62.zip
|
|
|
|
(7) At the command prompt, enter: quit.
|
|
|
|
You will need the PKUNZIP program to "unzip" this file (this
|
|
program is also in the pub/hytelnet/pc directory).
|
|
For information regarding the UNIX/VMS version, write to
|
|
Earl Fogel at fogel@skyfox.usask.ca.
|
|
For information regarding the Macintosh version, write to
|
|
Charles Burchill at burchil@ccu.umanitoba.ca.
|
|
|
|
6.0 Updating HYTELNET
|
|
|
|
New sites join the Internet almost on a daily basis. Members of
|
|
the LIB_HYTELNET mailing list, now numbering over 400 people in
|
|
twenty countries, forward information to me which I, in turn,
|
|
forward to the list. New and updated files may also be
|
|
downloaded via anonymous FTP from the access address above.
|
|
Completely new versions of the program are issued every two
|
|
months. To be added to the LIB_HYTELNET list, send a request to
|
|
scott@sklib.usask.ca. (Berkeley UNIX users can obtain
|
|
information about the latest version of the program by issuing
|
|
the following command at the system prompt: finger
|
|
scottp@herald.usask.ca.)
|
|
If you discover any new sites on the Internet, please send
|
|
full details to scott@sklib.usask.ca. You may also send
|
|
corrections to login procedures and/or telnet addresses.
|
|
|

|
|
|
7.0 The Future
|
|
|
|
The author is committed to keeping HYTELNET up-to-date, a task
|
|
that will be less burdensome if Internet users provide
|
|
assistance. Telnet-accessible sites will soon be available in
|
|
Africa, Asia, and Eastern Europe, and they will need to indexed.

1.0 Introduction
|
|
|
|
Navigating the Internet to locate and utilize OPACs and other
|
|
information systems is a considerable challenge for network
|
|
users. Users need to: (1) identify what telnet-accessible
|
|
systems are available on the network, (2) determine the telnet
|
|
addresses for these systems, (3) find out what information
|
|
resources are available on each system, (4) use the telnet
|
|
command to access desired systems, (5) login to these systems,
|
|
(6) search them, and (7) exit and return home to their local
|
|
systems.
|
|
Just over fourteen months ago, the only tools available to
|
|
network users to help them connect to telnet-accessible OPACS and
|
|
other library-oriented systems were two large directory files,
|
|
which were often referred to as the Art St. George directory and
|
|
the Billy Barron directory. Both directories provided telnet
|
|
site addresses and access instructions. These documents could be
|
|
obtained via anonymous FTP and stored on a local system.
|
|
Several telnet-based network access tools have evolved from
|
|
these two directories. These tools help users identify
|
|
appropriate information resources on remote systems, and they
|
|
automatically initiate telnet connections to systems that the
|
|
user selects. However, the user is still required to login to
|
|
remote systems, and the user must cope with searching a variety
|
|
of systems that may differ markedly from his or her local library
|
|
system.
|
|
The best known of these telnet-based network access tools
|
|
are LIBS from Sonoma State University, California; HYTELNET from
|
|
the University of Saskatchewan, Canada; LIBTEL from the
|
|
University of North Carolina; and CATALIST from the University of
|
|
Delaware. It is the first of these network access tools, the
|
|
LIBS Internet Access Software, that is the subject of this paper.

|
2.0 Brief History
|
|
|
|
The LIBS Internet Access Software, or the Sonoma software as it
|
|
is often called, is the work of Mark Resmer, Director, Computing,
|
|
Media, and Telecommunications at Sonoma State University in
|
|
California. The LIBS software first became available as the
|
|
program LIBS.COM in June 1991. On June 17, 1991, Art St. George
|
|
posted a message to the PACS-L list to thank Mark Resmer for
|
|
converting the document Internet-Accessible Library Catalogs and
|
|
Databases into a searchable database with the facility for
|
|
automatic telnet connection. Mark Resmer announced the first
|
|
"production quality" version (1.0) on July 30, 1991 along with a
|
|
message about a related list (inet-opacs@sonoma.edu) that he set
|
|
up to allow sites to receive announcements about the availability
|
|
of new versions of the software. On February 17, 1992, Mark
|
|
Resmer announced to the inet-opacs list that a version for BSD
|
|
4.3 UNIX (Berkeley UNIX) systems, LIBS.SH, had been "derived by
|
|
running it (the VMS version) through a series of mechanical
|
|
translation processes."
|
|
Since then the LIBS software has been further developed to
|
|
include not only telnet connections to the over 300 OPACs
|
|
available on the Internet, but also to numerous miscellaneous
|
|
databases, information services, and campus-wide information
|
|
systems. LIBS also provides for telnet connections to the other
|
|
currently available wide-area information access tools: Archie,
|
|
Gopher, Netfind, WAIS (Wide Area Information Servers), and World-
|
|
Wide Web (W3).
|
|
|
|
3.0 Current Version
|
|
|
|
The LIBS software is, like other access tools for networked
|
|
information resources, an ever-changing phenomenon. Currently
|
|
available are the VMS version, LIBS.COM 1.5A, and the UNIX
|
|
version, LIBS.SH 1.3U.
|
|
It is unfortunate for UNIX sites that the VMS and UNIX
|
|
versions are now out of synchronization, and we all await the
|
|
promised revision that will bring the two versions into line.
|
|
As with other software developments for access tools to
|
|
networked information resources, feedback on bugs and suggested
|
|
improvements is welcomed by the developer. These can be e-mailed
|
|
to Mark Resmer (resmer@sonoma.edu).

|
|
4.0 Obtaining LIBS
|
|
|
|
The LIBS software is available for anonymous FTP. The VMS file
|
|
is 345,267 bytes, and the UNIX file is 189,158 bytes. The latest
|
|
updates are May 15, 1992 for the VMS file and February 17, 1992
|
|
for the UNIX file.
|
|
Follow these directions to FTP the software from the Sonoma
|
|
archive:
|
|
|
|
(1) At your system prompt, type: ftp sonoma.edu.
|
|
|
|
(2) At the user prompt, type: anonymous.
|
|
|
|
(3) At the password prompt, type: your e-mail address in
|
|
the form user@host.domain (e.g.,
|
|
stanton@portia.csu.murdoch.edu.au.).
|
|
|
|
(4) At the command prompt, type: cd pub.
|
|
|
|
(5) At the next command prompt, type: get libs.com (or get
|
|
libs.sh).
|
|
|
|
(6) At the next command prompt, type: quit.
|
|
|
|
You do not need to use binary mode to transfer these files.
|
|
|
|
5.0 System Requirements
|
|
|
|
LIBS runs under VMS 5.0 (or later) or BSD 4.3 UNIX. The standard
|
|
terminal for both LIBS versions is a VT100 (or VT100 emulation).
|
|
Apart from a connection to the Internet, or regional TCP/IP
|
|
network, VMS systems must also have appropriate TCP/IP software.
|
|
For example, a product such as TGV Multinet or Wollongong is
|
|
ideal. Users of Digital's UCX or the public domain CMU-TEK
|
|
software will find that the implementation of telnet in these
|
|
packages is not sufficient for all purposes required by the LIBS
|
|
software (i.e., sites that require TN3270 cannot be accessed).
|
|
UNIX users do not need any additional TCP/IP software, since
|
|
TCP/IP functionality is standard on nearly all UNIX systems.
|
|
However, TN3270 software is required and can be found at many FTP
|
|
sites.
|
|
|
|
+ Page 7 +
|
|
|
|
6.0 Installation
|
|
|
|
For most sites, it is probably ideal if the software is installed
|
|
centrally and updated regularly by a system administrator. This
|
|
is preferable to users having their own copies of the script in
|
|
their own account.
|
|
The LIBS software is easy to install, and updates, although
|
|
irregular, have been frequent.
|
|
VMS administrators can simply copy the DCL command file into
|
|
a common area, grant world read access, and install an
|
|
appropriate abbreviation in the system login.com to ensure that
|
|
users can easily run the software.
|
|
UNIX administrators can take a similar approach, copying the
|
|
shell script into a common area such as usr/local/bin and setting
|
|
the correct access permissions.
|
|
|
|
7.0 Maintenance
|
|
|
|
The only maintenance requirement is to obtain a replacement for
|
|
the software when a new version is announced on the mailing list,
|
|
remove the older version, and install the replacement version.
|
|
|
|
8.0 Local Customization
|
|
|
|
Some sites may choose to edit the software to reduce the number
|
|
of telnet sites that their campus network users can access via
|
|
the LIBS software. Other sites may choose to emphasize access to
|
|
local resources and, rather than run the LIBS software as is,
|
|
append it to local software. This can easily be done. At
|
|
Murdoch University, the LIBS software is appended to a local
|
|
software application (NetLib). In this way, campus network users
|
|
have an initial menu with options for access to local OPACs in
|
|
their state, to OPACs in other states and territories of
|
|
Australia, and to international OPACs. Like the LIBS software,
|
|
the NetLib software is made available for both VMS and UNIX
|
|
systems.

|
9.0 Evaluation of LIBS
|
|
|
|
The features of the LIBS software can be examined in four areas:
|
|
(1) software, (2) the user interface, (3) coverage of network
|
|
resources, and (4) connections to other wide-area information
|
|
access tools.
|
|
|
|
9.1 Software
|
|
|
|
Overall, the LIBS software works very well. The only observation
|
|
that most sites would make, and that Mark Resmer mentions in his
|
|
announcements, is the time it can take to load the large script
|
|
file.
|
|
|
|
9.2 User Interface
|
|
|
|
The initial screen offers a menu item for first-time users of
|
|
LIBS (see Figure 1, item 6). [1] By choosing this menu item,
|
|
users can view basic information about utilizing remote systems
|
|
with LIBS, which includes an explanation of how to exit from
|
|
these systems.

|
|
|
|
When a user selects a particular information resource, the
|
|
following screen will display a description of that resource (see
|
|
Figure 2 for an example). Most importantly, the description is
|
|
provided prior to the telnet connection and ensures that the user
|
|
is informed of login instructions and terminal type information.
|
|
The user is always given the options to connect (or not connect)
|
|
to the resource and to exit from the LIBS program.

Figure 2. EDIN Screen
|
|
-----------------------------------------------------------------
|
|
|
|
EDIN
|
|
|
|
The Pennsylvania State Data Center maintains this database of
|
|
population and economic statistical data which includes, among
|
|
other things, the Commerce Business Daily. EDIN is accessible
|
|
through the EBB service of Penn State.
|
|
|
|
Note the following instructions carefully
|
|
|
|
Once you are connected:
|
|
|
|
Type: info <return> at the first prompt
|
|
Type: EDIN <return> at the next prompt
|
|
|
|
Press Control-C Q <return> to exit at any time
|
|
|
|
Do you want to connect now? (Y or N):
|
|
-----------------------------------------------------------------
|
|
|
|
There is a consistent user interface; however, the numbered menu
|
|
options are not always in alphabetical order. This is
|
|
particularly true of the screen for "Scientific
|
|
Databases/Information Systems."
|
|
The screen messages at all times assist the user to navigate
|
|
the system.

|
9.3 Coverage of Network Resources
|
|
|
|
LIBS provides access to OPACs, CWIS systems, and other resources.
|
|
|
|
9.3.1 OPACs
|
|
|
|
The LIBS software provides users with access to over 300 OPACs.
|
|
The initial screen allows the user to select between United
|
|
States OPACs and OPACs in other countries. The United States
|
|
menu presents a numbered display of states in alphabetical order.
|
|
The other menu presents a numbered display in alphabetical order
|
|
by country. Fourteen countries are included: Australia, Canada,
|
|
Finland, Germany, Hong Kong, Ireland, Israel, Mexico,
|
|
Netherlands, New Zealand, Spain, Sweden, Switzerland, and the
|
|
United Kingdom.
|
|
Once selected, some of these options include OPAC coverage
|
|
and collection strength information. This information is
|
|
provided for sites that have given these details to Art St.
|
|
George. This type of information is not comprehensive throughout
|
|
LIBS (and also potentially not up-to-date) since it depends on
|
|
the contributions made by individual sites to the compiler of the
|
|
directory.
|
|
|
|
9.3.2 Campus-Wide Information Systems
|
|
|
|
The initial screen also provides access to campus-wide
|
|
information systems that are currently available via telnet.
|
|
These systems are available in Canada, Germany, Switzerland, the
|
|
United Kingdom, and the United States. Again, this is a numbered
|
|
alphabetical listing; however, the states of the United States
|
|
are interspersed with entries for other countries.
|
|
|
|
9.3.3 Other Databases and Information Services
|
|
|
|
Numerous databases and information services that cover a wide
|
|
range of topics are included. In earlier versions of the LIBS
|
|
software, these resources were presented as a straight
|
|
alphabetical listing. The current version provides for subject-
|
|
based access in five broad areas (see Figure 3).

-----------------------------------------------------------------
|
|
|
|
Here is an explanation of these choices:
|
|
|
|
o Agricultural: Two options are available in the current
|
|
version of LIBS. These options are CSU Fresno
|
|
Agricultural Information and PENpages.
|
|
|
|
o Arts/Humanities: The three options are the American
|
|
Philosophical Association, the Catalogue of Projects in
|
|
Electronic Text, and the Dartmouth Dante Databases.
|
|
|
|
o Business: The option here is for EDIN, a database
|
|
accessible through Pennsylvania State University.
|
|
|
|
o Education: Included here are two options. The first is
|
|
for the International Centre for Distance Learning
|
|
(Open University) and the second is for the National
|
|
Education BBS.
|
|
|
|
+ Page 12 +
|
|
|
|
o Science: This subject area is well served with a total
|
|
of sixteen options that include databases and bulletin
|
|
board services. They are:
|
|
|
|
American Mathematical Society BBS (e-MATH)
|
|
Brookhaven National Laboratory
|
|
Environmental Protection Agency
|
|
Online Library System
|
|
GenBank--Gene Sequence Information
|
|
Lunar and Planetary Institute (LPI)
|
|

|
NASA Extragalactic Database
|
|
NASA News
|
|
NASA Spacelink
|
|
National Nuclear Data Center
|
|
National Science Foundation Information Service
|
|
National Space Science Data Center
|
|
Southwest Research Institute Data
|
|
Analysis/Display System
|
|
Supernet International
|
|
U.S. Naval Observatory Automated Data Service
|
|
World Ocean Circulation Experiment
|
|
|
|
o Weather/Time/Earthquake Information: The three options
|
|
here are for Earthquake Information from the USGS and
|
|
the University of Washington, the National Bureau of
|
|
Standards Time Service, and Weather Information from
|
|
the University of Michigan.
|
|
|
|
o Other: This option is a miscellany of 10 types of
|
|
services, including the Chess Server, DRA Library of
|
|
Congress catalog, FEDIX/MOLIS, and the Geographic Name
|
|
Server.
|
|
|
|
9.4 Connections to Other Wide-Area Information Access Tools
|
|
|
|
This front-menu option is a welcome revision to the earlier
|
|
versions of LIBS. The user can now carry out telnet sessions
|
|
with five network access tools. Each of these options includes a
|
|
description and, as elsewhere in LIBS, the option to connect.
|
|
The tools listed are Archie, Gopher, Netfind, WAIS, and
|
|
World-Wide Web. The Gopher Server available here is the
|
|
University of Minnesota's Gopher. The WAIS option is for a
|
|
connection to the Thinking Machines Server site. The World-Wide
|
|
Web option connects the user to the site in Cern, Switzerland.
|
|
Helpful descriptions of these wide-area information access
|
|
tools are provided in LIBS.
|
|
|
|

|
|
|
|
10.0 Comparison With HYTELNET
|
|
|
|
The LIBS software may be compared with another network access
|
|
tool that provides automatic telnet connections: HYTELNET, the
|
|
work of Peter Scott (University of Saskatchewan). HYTELNET uses
|
|
a hypertext interface for accessing networked information
|
|
resources. Like the LIBS software, in addition to automatic
|
|
telnet connections to information resources, it provides the user
|
|
with telnet connections to other access tools such as Archie,
|
|
Gopher, WAIS, and World-Wide Web.
|
|
HYTELNET evolved from a memory-resident, DOS-based online
|
|
directory to telnet-accessible sites to an access tool for both
|
|
VMS and UNIX systems. Initially based on Billy Barron's
|
|
directory (UNT's Accessing On-Line Bibliographic Databases), it
|
|
now has a much wider scope. Its coverage is very similar to the
|
|
LIBS software, but it is currently much more extensive. What it
|
|
does not have is the subject-based approach to accessing
|
|
information resources.
|
|
While the current version of LIBS.COM gives users access to
|
|
one site with a Gopher Server, one site with a WAIS Server, and
|
|
one site with a World-Wide Web, this is not the case with
|
|
HYTELNET. The latest version of HYTELNET (version 6.2) offers
|
|
more than one site for users to explore these additional access
|
|
tools.
|
|
The disparity in coverage now apparent between the LIBS
|
|
software and HYTELNET may have implications for the longevity of
|
|
the LIBS software. It also raises the question of how sites
|
|
choose which type of software to implement for their local
|
|
setting. Another question that is now becoming an issue on some
|
|
campuses is the best way to accommodate access to telnet
|
|
resources while implementing a Gopher Server. There are varying
|
|
solutions in place around the networks.
|
|
|
|
11.0 Conclusion
|
|
|
|
The LIBS Internet Access Software provides a simple and easy-to-
|
|
use menu system that assists both new and experienced network
|
|
users in accessing the wealth of information resources on the
|
|
Internet. The software is available free of charge and its
|
|
installation is simple. The developer announces new versions and
|
|
welcomes information about new sites and software bugs. The LIBS
|
|
software is highly recommended for any and all Internet sites
|
|
with a need to provide users with easy access to networked
|
|
information resources.
