[Koha] Koha getting authorities and bibliographic records to link

All, After migrating and indexing both the authority and bibliographic records, could someone direct me to the documentation about how to get the two to connect? For example, how does merge_authority.pl work with /usr/share/koha/bin/link_bibs_to_authorities.pl ? The merge_authority.pl says that it is "a script that rebuild thesaurus from biblio table" I'm sure that I'm not finding all the documentation available, and I apologize in advance, and thanks for your help. -- Linda Culberson lculber@mdah.state.ms.us Archives and Records Services Division Ms. Dept. of Archives& History P.
