1.0 Introduction

1.1 What is hypertext?  What are its origins?

    The short answer: "Non-sequencial writing"
    see: --Bush, V. (1945) "As We May Think" Atlantic Monthly,
	 176/1, July, pp. 101-108.
	 --Nelson, T.H. (1981), "Literary Machines" (self-
	   published and electronic versions available)

    The long answer:

    The term "hypertext" eludes a simple definition.  The
easiest explanation might be "a non-linear grouping of linked
nodes".  Ted Nelson, who coined the phrase in his book "Literary
Machines", called it "nonsequencial writing", and it was only later
that hypertext was considered a medium limited to the computer.  While
the idea of a non-linear form of writing can be traced back
centuries, the first model of a electronic based system which
could link various blocks of text appears to be a 1945 article in
the Atlantic Monthly by Vannevar Bush entitled "As We May Think".
     By 1945, Bush had realized that an era of information was
approaching.  He commented:
 "The summation of human experience is being expanded at a
prodigious rate, [but] the means we use for threading through the
consequent maze to the momentarily important item is the same as
was used in the days of square-rigged ships."
    Bush wrote of a "memex", a conceptual machine that could store
vast amounts of information, in which a user had the ability to
create information "trails": links of related text and
illustrations.  This trail could then be stored and used for
future reference.  Bush believed that using this associative
method of information gathering was not only practical in its own
right, but was closer to the way the mind ordered information.
     Ted Nelson picked up on Bush's ideas in his book "Literary
Machines" (1981).  His ideas revolved around a system called
"Xanadu" in which a user could create a "hypertext", a document
consisting of linked "nodes".
"A link is simply a connection between parts of text or other
material.  It is put in by a human.  Links are made by
individuals as pathways for the reader's exploration; thus they
are part of the actual document, part of the writing."
    A node is simply a discrete unit of text, graphics, sound, or
whatever.  Within each node, there are links to other nodes.
This is the basic structure of a hypertext.  Nelson took Bush's
ideas a step further with his Xanadu project-- he envisioned an
entire "docuverse" of interconnected, networked hypertext; a
system that would inevitably replace print publishing.  But more
on that concept later.
     The concept of "hypertext" has changed a lot since Bush and
Nelson first proposed the idea.  The notions of what a hypertext
is and what it can and cannot do have blurred.  In my opinion,
all printed texts are not necessarily going to benefit by being
turned into hypertext documents.  Hypertext is not a panacea for
information handling, nor is it going to revolutionize the way
humans think and interact...
     There are many arguments as to the exact definition of
"hypertext".  When Nelson first coined the phrase he was simple
referring to "nonsequencial text", which could be accomplished
just as easily on paper as it could on a computer.  Since then,
the definition has vastly expanded to encompass a wide variety of
computer-related information systems.  I feel that attempting to
find a definitive response to the question "What is hypertext?"
is not only impossible, but unnecessary.  I see hypertext as more
of a set of tools, not all of which need to be implemented for
the end result to be considered a "hypertext system" or
"hypertext document".  The tools used for an on-line card
catalogue are much different than of a computerized medical
tutorial or a hypertext novel.

1.2 What is the difference between hypertext and hypermedia?

	Both terms are nebulous, but for the most part, hypertext
is the more general term.  Hypermedia refers to the ability to use
several "media" (text, graphics, sound, video) in a single "document"
(or "presentation", etc).

1.3 Where can I get info on hypertext on the Internet?

1.3.1 Usenet Newsgroups

     Try these newsgroups:

     alt.hypertext
     comp.infosystems.*

1.3.2 Bitnet lists

3.0 - Selected Bibliography

3.1 Recommended

Here are some books I'd recommend:

Berk, Emily, ed., "Hypertext/hypermedia handbook" /  New York : Intertext
     Publications : McGraw-Hill, c1991.  xvii, 583 p. : ill. ; 24 cm.
notes: pretty complete, starts with the basics and moves on to more
       advanced topics.  Includes many case studies and large
       bibliography.

McKnight, Cliff, "Hypertext in Context" / Cambridge University Press, 1991
notes: very well written, slim volume deals with most of the major issues
of hypertext theory and design.

Seyer, Philip C., "Understanding hypertext : concepts and
     applications" /  1st ed.  Blue Ridge Summit, PA : Windcrest, c1991. xii,
     263 p. : ill., maps ; 25 cm.
notes: well written.

Barrett, E., ed., "Text, ConText, and HyperText" / MIT  Press, 1988.
notes: sort of the classic.  Very, um, "erudite".  The sequel is
"The Society of Text" (1989).


3.2. Bibliographies

There are several published bibliographies of books, articles, etc., on
hypertext issues that I know of:

Lamb, Annette C.  Emerging technologies and instruction :
     hypertext, hypermedia, and interactive multimedia : a selected
     bibliography /  Englewood Cliffs, N.J. : Educational Technology
     Publications, c1991.  64 leaves ; 29 cm.

Knee, Michael.  Hypertext/Hypermedia : an annotated bibliography
     /  New York : Greenwood Press, 1990.  xv, 178 p. ; 24 cm.

Texas A&M University also publishes an electronic bibliography, but I
can't find it on the Internet.


3.3 Periodicals

???

4.0 - On-Line hypertext services/systems/projects

4.1 World Wide Web (WWW)

[Copied from a post by joe@athena.mit.edu (Joseph C Wang)]

WHAT IS IT?
-----------
World Wide Web (WWW) is a hypertext project which seeks to build a
world wide network of hypertext links.  There are several different
browsers for this system including a simple tty interface.  For a
demos of the terminal browsers for WWW, telnet to the following sites:

 telnet info.cern.ch or telnet 128.141.201.74 (SWISS)
 telnet eies2.njit.edu or telnet 128.235.1.43 (USA [NJ])
 telnet vms.huji.ac.il or telnet 128.139.4.3  (ISRAEL)
 telnet info.funet.fi or telnet 128.214.6.100 (FINLAND)

Login as "www"


4.2 Wide Area Information Services (WAIS)

from "Overview of WAIS" by Brewster Kahle:
"The Wide Area Information Servers system is a set of products supplied
 by different vendors to help end-users find and retrieve information over
 networks.  Thinking Machines, Apple Computer, and Dow Jones initially
 implemented such a system for use by business executives.  These products
 are becoming more widely available from various companies."

for more info FTP to quake.think.com /pub/WAIS

to experience a WAIS server, you can telnet to quake.think.com
and login as "wais".


4.3 Hytelnet

[Copied from the WHATIS file included in the hytelnet package]

	HYTELNET is designed to assist you in reaching all of the
		  INTERNET-accessible libraries, Freenets, CWISs,
		  Library BBSs, & other information sites by Telnet.

	HYTELNET is designed specifically for users who access
		  Telnet via a modem or the ethernet from an
		  IBM compatible personal computer.

	HYTELNET, when loaded, is memory-resident. Once loaded hit
		  Control + Backspace to activate the program. To
		  leave the program temporarily hit ESC. To remove
		  from memory hit ALT-T while in the program.

Check out Archie for the closest FTP site that has HYTELNET.


4.4 Gopher

[This info is copied from the gopher FAQ file]

Q0:  What is Gopher?

A0:  The Internet Gopher client/server provides a distributed
     information delivery system around which a world/campus-wide
     information system (CWIS) can readily be constructed.   While
     providing a delivery vehicle for local information,  Gopher
     facilitates access to other Gopher and information servers
     throughout the world.

Q1:  Where can I get gopher?

A1:  via anonymous ftp to boombox.micro.umn.edu.  Look in the directory
     /pub/gopher


Q2:  What do I need to access gopher?

A2:  You will need a gopher "client" program that runs on your local PC
     or workstation

     There are clients for the following systems.  The directory
     following the name is the location of the client on the anonymous
     ftp site boombox.micro.umn.edu (134.84.132.2) in the directory
     /pub/gopher.

      Unix Curses & Emacs   :  /pub/gopher/Unix/gopher1.02.tar.Z
      Xwindows              :  /pub/gopher/Unix/xgopher1.1a.tar.Z
      Macintosh Hypercard   :  /pub/gopher/Mac_client/
      Macintosh Application :  /pub/gopher/Mac_client/
      DOS w/Clarkson Driver :  /pub/gopher/PC_client/
      NeXTstep              :  /pub/gopher/NeXT/
      VM/CMS                :  /pub/gopher/Rice_CMS/ or /pub/gopher/Vienna_CMS/
      VMS                   :  /pub/gopher/VMS/

     There are also a number of public telnet login sites available.
     The University of Minnesota operates one on the machine
     "consultant.micro.umn.edu" (134.84.132.4) See Q3 for more
     information about this.  It is recommended that you run the client
     software instead of logging into the public telnet login sites.  A
     client uses the custom features of the local machine (mouse,
     scroll bars, etc.)  A local client is also faster.

Q3:  Where are there publicly available logins for gopher.

A3:  Here is a short list, use the site closest to you to minimize
     network lag.

     Hostname                  IP#              Login   Area
     ------------------------- ---------------  ------  -------------
     consultant.micro.umn.edu  134.84.132.4	gopher  North America
     gopher.uiuc.edu           128.174.33.160   gopher  North America
     gopher.uwp.edu	       131.210.1.4      gopher  North America
     panda.uiowa.edu           128.255.40.201	panda   North America
     info.anu.edu.au           150.203.84.20    info    Australia
     gopher.chalmers.se        129.16.221.40    gopher  Sweden

     It is recommended that you run the client software instead of
     logging into the public telnet login sites.  A client uses the
     custom features of the local machine (mouse, scroll bars, etc.)  A
     local client is also faster.

4.5 Project Guttenberg

	Project Guttenberg scans in non-copyrightten books and creates
ASCII files out of them.  For more information contact Michael Hart
(HART@vmd.cso.uiuc.EDU).  I believe at least some of the electronic
books (Etexts) are on Sim-tel pd1:<msdos.books>
