Yes, I see... However, as we have punctuation in thousands of records, wouldn't be possible to enable input in bibliogr. fields which are defined as containing authorities? In this way, adding a comma wouldn't be a problem. Would anyone know how to enable this? In fact, input in this fields is not allowed (except BiblioAddsAuthorities preference ON, which would create duplicate records). I would also like to ask the question about MergeAuthoritiesOnUpdate Function. Normally, updating bibliogr. records with the authority (when MergeAuthoritiesOnUpdate is ON) rewrites *all *the subfields - also for ex. relator terms (700$e in MARC21 - translator ecc.); but some fields (700$e) are not used in authorities but in biblios, so updating biblios simply deletes this information. Is there a way how to exclude this subfield from copying from authorities to the biblios?- Hide quoted text - Thank you very much Ondrej Mlecka Rome
