22) What repositories of TeX material are available, and how can I access
    them?
 
    There are many repositories of TeX material available. Most of them
    also have a mail server, i.e., a program that will send you files
    via electronic mail. Here are some of the better ones:
      - In the US, the archive at ymir.claremont.edu (134.173.4.23) has 
        a lot of PD TeX software, and even if it's not explicitly stated, 
        much of the software mentioned in this document is available there.
        Anonymous ftp is supported, as is a mail server. Unfortunately, 
        executables are not available through the mail server. Send a 
        message containing the line ``help'' to MAILSERV@ymir.claremont.edu.
      - The archive at Clarkson University, although out of date, still has
        some things of interest. Use anonymous ftp to get files from 
        sun.soe.clarkson.edu (128.153.12.3). An archive server is available
        if you can send mail to the United States. Send a one-line message
        ``help'' to archive-server@sun.soe.clarkson.edu and it will send
        you a file describing how to use it more fully. If you have 
        problems, contact archive-management@sun.soe.clarkson.edu
      - In the United Kingdom, you can get TeX-related material from the
        UK TeX archive at the University of Aston. (FTP access is also
        available for people on JANET or the Internet. Use anonymous ftp
        to tex.ac.uk (134.151.40.18). You will be placed in the root of
        of the [tex-archive]. Telnet access is also allowed, to permit
        more intelligent browsing. Use the username PUBLIC and the same
        password. A known file is [tex-archive]000directory.list.) For 
        electronic mail access, send a message to texserver@tex.ac.uk. The 
        first non-blank line of the message must contain a valid TeXserver
        command (help, directory, files, whereis, search, or path). The 
        program will then mail you a response notifying you that your 
        request has been received. If you fail to get a response from the
        TeXserver, you may need to use the ``path'' command to help the 
        program out. For Internet users the return address is of the form 
        name%site@nsfnet-relay, while for Bitnet and EARN it is 
        name%site@earn-relay (i.e., include a line that says 
        ``path name%site@nsfnet-relay'' along with a line containing 
        ``help''). Note that the old three hyphen format is obsolete, but 
        still accepted by the program for backward compatibility.
      - archive.cs.ruu.nl (131.211.80.5) also contains a substantial TeX
        archive with ftp access. To use it via email, send a message
        containing the line ``help'' to mail-server@cs.ruu.nl. This mail 
        server can send binary files in a variety of different formats.
      - In Germany, the host rusinfo.rus.uni-stuttgart.de (129.69.1.12)
        is an anonymous ftp site with much TeX material. In particular
        it is the definitive source for new font selection scheme in
        LaTeX, for emtex (TeX for the IBM PC, see question 19), and contains
        a set of hyphenation patterns for languages other than English. To
        use it via email, send a message containing the line ``help'' to
        mail-server@rusinfo.rus.uni-stuttgart.de.
      - There are LISTSERV facilities for TeX at LISTSERV@DHDURZ1.BITNET. 
        Send a message containing the line ``help'' to this address.
      - Another aggressively maintained archive is FILESERV@SHSU.BITNET.
        Sending a message with the line HELP will get help, and
        SENDME FILELIST will get an annotated listing of all packages 
        available there. The archive is accessible via anonymous ftp to
        the host niord.shsu.edu (192.92.115.8).
      - For users on BITNET, access to anonymous ftp for some files can
        be obtained indirectly by sending mail to BITFTP@PUCC.BITNET.
        Send a message containing the line ``help'' to this address for
        more information.
     
    There is also the DECUS TeX collection, a collection of TeX material
    for VMS, Unix, MS-DOS, and the Macintosh. It is available via 
    anonymous ftp from wuarchive.wustl.edu (128.252.135.4) in ./decus/tex.
    It can also be obtained from the DECUS Library (reference number 
    VS0058) in the US, or through your DECUS office outside of the US. To 
    contact the DECUS Library, send mail or call:
                 The DECUS Program Library
                 219 Boston Post Road BP02
                 Marlboro, MA 01752-1850
                 (508)480-3418
    or send electronic mail to the DECUS TeX Collection Editor, Ted 
    Nieland, at decus_tex@nieland.dayton.oh.us.

    Peter Flynn which appeared in TeXhax, volume 90, issues 45-47 (in
    May 1990).
