+ <title>NLI-Z39.50 - a Natural Language Interface for Libraries</title>
+ <para>
+ Fernuniversität Hagen in Germany have developed a natural
+ language interface for access to library databases.
+ <!-- <ulink
+ url="http://ki212.fernuni-hagen.de/nli/NLIintro.html"/> -->
+ In order to evaluate this interface for recall and precision, they
+ chose Zebra as the basis for retrieval effectiveness. The Zebra
+ server contains a copy of the GIRT database, consisting of more
+ than 76000 records in SGML format (bibliographic records from
+ social science), which are mapped to MARC for presentation.

+ <title>ULS (Union List of Serials)</title>
+ <para>
+ The M25 Systems Team
+ has created a union catalogue for the periodicals of the
+ twenty-one constituent libraries of the University of London and
+ the University of Westminster
+ (<ulink url="http://www.m25lib.ac.uk/ULS/"/>).
+ They have achieved this using an
+ unusual architecture, which they describe as a
+ ``non-distributed virtual union catalogue''.
+ </para>
+ <para>
+ The member libraries send in data files representing their
+ periodicals, including both brief bibliographic data and summary
+ holdings. Then 21 individual Z39.50 targets are created, each
+ using Zebra, and all mounted on the single hardware server.
+ The live service provides a web gateway allowing Z39.50 searching
+ of all of the targets or a selection of them. Zebra's small
+ footprint allows a relatively modest system to comfortably host
+ the 21 servers.
