\section{From the network}

The UK \TeX\ Archive (Internet `Daughter' archive) on {\tt
ftp.tex.ac.uk} is part of a collaborating network of archives
organised by the \TeX\ Users Group known as CTAN (Comprehensive \TeX\ 
Archive Network).  The three main archives now follow the same
structure and have identical files ({\tt ftp.tex.ac.uk}, {\tt
  ftp.shsu.edu} and {\tt ftp.uni-stuttgart.de}).

The preferred access method to the UK \TeX\ Archive is using the {\em
gopher} program which has a set of useful indexes to help you locate
what you are looking for, but Internet {\em ftp} access is also very
common.  JANET users may only access the machine using the {\tt
ft-relay} site, as it has no X25 connection. 

The CTAN archives all run an enhanced {\em ftp} server which supports
dynamic compression, uncompression, and archive creation options.
Fetch the top-level file {\tt README.archive-features} for
information.  The server also supports site-defined commands to assist
you. Please read {\tt README.site-commands} for a brief overview.

The main directories which make up CTAN are listed below; readers are
referred to David Jones' {\em Index of \TeX\ Styles and Macros} for
details of macro packages and individual style files. This can be
found in CTAN as {\tt info/tex-styles-and-macros.txt}

Details of where to find public domain, or shareware,
\TeX\ packages for different machines and operating
systems are given in
Figure \ref{systems}. Some readers may prefer to purchase a commercial
package, with support. {\em Neither CTAN not \ukt\ are in a position to
offer support for software in the archive}.

Please report any problems with CTAN archives via e-mail to {\tt
ctan-mgr@shsu.edu}. The entire archive will be available on CDROM from
early 1994; details will be given in the next issue of \BV.

\section{Unix tapes}
For a complete Unix \TeX\ distribution, a
1/4 inch cartridge, QIC-120 or QIC-150 format (DC600A or DC6150)
can sent with envelope {\em and} stamps for return postage to:

    Cripps Computing Centre, \\
    University of Nottingham, \\
    Nottingham NG7 2RD
\end{quote}
Due to currency exchange, this service is offered only within the UK.

\section{PC and Mac disks}
From January 1994 the \ukt\ will start distributing an em\TeX\ kit for
PCs, and an Oz\TeX\ kit for Macintosh, for a small fee to cover
copying and postage costs, and the shareware fee for Oz\TeX. Details
will be given in the next issue of \BV.

%For copies of em\TeX\ (for OS/2, PC-DOS and MS-DOS), and a free %
%catalogue detailing other disk formats, precompiled fonts and lots of
%other goodies, you can also contact: Eigen PD Software, P.O. Box 722,
%Swindon SN2 6YB (tel: 0793-611270) (JANET e-mail address: {\tt
%kellett@uk.ac.cran.rmcs})

Enquiries for \TeX\ for the Atari ST etc. can be directed to:
The South West Software Library, P.O. Box 562, Wimborne, Dorset BH21 2YD
(JANET e-mail address: {\tt mdryden@uk.co.compulink.cix})
