Can anyone tell me if is it possible to issue an item without the reference to the barcode? Can i issue for instance with the reference to the call number?

No, because the call number may not necessarily refer to one, and only one, item. If your call numbers _are_ unique to each item, then I suppose you could use the call number both as a call number and as a barcode, putting it in both MARC subfields.

Second question: How can i make a search to the catalog that return to me all the existing records? I'm testing koha and i still don't figure how can i do it...with the software i have in "my" library (Basis TechLib) i can do that with "*"...

Try this: 1. Choose a MARC subfield that's in all of your records -- perhaps "title" (MARC 21 subfield 245$a). 2. Do a catalog search against this subfield (from the lower section of the intranet catalogue search screen), setting the operator to "Is greater or equal to" and using a space as the search term. That should return everything in your catalog. Stephen -- Stephen Hedges Skemotah Solutions, USA www.skemotah.com -- shedges@skemotah.com
