How can we activate z39.50 in Koha In order to obtain records from the World catalog and other libraries

You don't need to "activate" anything, you just need to have some Z39.50 servers added to Koha, which would normally have been done during the installation process. http://manual.koha-community.org/3.16/en/additionaladmin.html#z3950admin That manual entry also links to http://irspy.indexdata.com/ and http://www.loc.gov/z3950/ which are resources for finding Z39.50 servers you can add to Koha manually. -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
