Uniform titles will link only to 130, 630, 730, and 830 tags. 240 tags are uniform title tags and should also be linked. In addition, the auto create function should but does not create a 130 uniform title authority from a 240 bibliographic entry.
Hi Jess, can you explain a bit more about the link? Where should the link display and where should it link to?
Uniform titles in MARC21 field 240 are used if there is a primary access point present. For examples laws use the following combination: 110 $a Canada 240 $a Laws, etc. 245 $a .... Or in literary works: 100 $a Cervantes Saavedra, Miguel de 240 $a Don Quijote de la Mancha 245 $a .... The corresponding authority records should not link to the 240 field directly, but to the 110/240 or 110/240 combination. For the first example the authority record should be: 110 $a Canada $t Laws, etc. and for the second example: 100 $a Cervantes Saavedra, Miguel de $t Don Quijote de la Mancha This means Koha should be able to use one authority field to link to two fields in the bibliographic record. Koha should not use 130 Uniform title authority records to link to 240 fields.
