For each WWW search interface of the target catalogs, a structure description file is provided which allows entry into the CGI program. The structure description file describes the structure of the respective search form and the structure of the resulting hit lists. Important information about the search form is the names of the WWW server, the search fields, and the CGI program of the target catalog that performs the search. The CGI program of the KVK then transfers the search queries in the KVK in the correct syntax to the correct fields of the target catalog. Important elements of the hit list are the short titles of the hits and the URL links to the full title dis. </p> <div class="mw-heading mw-heading2"><h2 id="References">References</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Karlsruher_Virtueller_Katalog&action=edit&section=2" title="Edit section: References"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li>Michael Mönnich: <i>KVK.
