 ====== Z39.50======
 **[[http://www.loc.gov/z3950/agency/|Z39.50]]** is an international client/server protocol for searching bibliographic data. It can use the Internet Protocol (TCP/IP), which makes the databases on a server available from almost anywhere around the globe. It is widely used, for example, in on-line library catalogues. It allows a user to search one or more databases and retrieve the results of the query.
-Greenstone has support for Z39.50, both as a client (Greenstone 2 and 3) and a server (Greenstone 2). GLI can download MARC records using Z39.50 and MARCXML records using SRU. These records can then be included in a collection. This support is enabled by default.

-The Greenstone 2 run-time can also act as a client to multiple Z39.50 servers, and a Z39.50 server program is also available.  This support is not enabled by default, and recompilation is needed to enable it. To do this, you need the source code. If you don't already have the source, download the version of the source code component that matches the distribution you are using.

 Z39.50 support in Greenstone is based around the YAZ toolkit, written by [[http://www.indexdata.dk/|IndexData]]. We are currently using YAZ version 2.1.4. This is included in the Greenstone 2 distribution without modification. Greenstone links against the ''libyaz.a'' library. We have also written ''yaz_zclient.h/cpp'', which is based on the sample ''client.h/cpp''. This is found in //greenstone/runtime-src/src/z3950//.

     * To enable iconv or xml2, edit greenstone\runtime-src\win32.mak, and remove HAVE_ICONV=0 and/or HAVE_LIBXML2=0 from the make command for Yaz. You'll need to install these libraries.

+===== Using the Greenstone 2 Z39.50 client =====
 Once Greenstone 2 has Z39.50 support compiled in, it can act as a client to multiple z39.50 servers. The file ''Greenstone/etc/packages/z3950/z3950.cfg'' specifies a list of servers to connect to. By default, no servers are set up, although the config file comes with one (commented out) example Z39.50 server, for the United States' Library of Congress.

 Greenstone will display a new "collection" for each server listed.
