We discovered that when you create a Fast Add/Temp record from Cataloging > New Record > Fast Add the Set Library defaults to Atchison (the first branchcode in the table), rather than the Set Library for that session. When you create a Fast Add/Temp record for Circulation, the Set Library defaults correctly. When you create any other kind of framework record from Cataloging, the Set Library defaults correctly. Looks like addbiblio.pl was modified to take the branch in from the circulation page (according to the new Fast Add at barcode scan dev we reimplemented from Harley), but that parameter is absent if you come at Fast Add from Circulation -> Fast Add or Cataloging. I think this can be fixed with a simple "default" value set on these lines: addbiblio.pl line 862 additems.pl line 592
