Hi All, I am working my way through your guide on Setting Bibliographic Data Parameters in Koha. I have got through most of the MARC21 tags I am going to set up, but am unclear about the function of the "search also" field in the Edit MARC subfields contraints for framework default page. For example In Tag 100a I entered the following in the "search also" field (as per what was aleady in the installation) '100b','100c','100q','100d','100e','110a','110b','110c','110d','110e','700a','700b','700c','700q','700d','700e','710a','710b','710c','710d','710e','720a','720e','900a' Should I then cross reference in other fields within all the 100 tag subfirelds that I am defining - Such as putting the following in Tag 100b '100a','100c','100q','100d','100e','110a','110b','110c','110d','110e','700a','700b','700c','700q','700d','700e','710a','710b','710c','710d','710e','720a','720e','900a' Or do you just put the search also information into the field that is directly linked to a Koha table? If you can help that would be great, Many thanks, Jenny Collery IPPA, the early childhood organisation Kind Regards Jenny Collery IPPA, The Early Childhood Organisation<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Unit 4 Broomhill Business Complex Broomhill Road Tallaght Dublin 24 Tel: 01 4630010 DDI: 01 4630027 Fax: 01 4630045 Web: <http://www.ippa.ie/> www.ippa.ie IPPA, the Early Childhood Organisation, is funded by the Irish Government under The National Development Plan 2000-2006 and the European Union through the European Structural Fund.
