There are times when having the same barcode assigned to different records might be useful. Here at the Lunar and Planetary Institute I create a catalog record for special issues of journals, an analytic. For example, a recent issue of Astrophysics and Space Science was a special issue with the title Magnetic fields and star formation : theory versus observations. I created a separate catalog record for that, however, it will be bound in a volume with other issues of and given a barcode for the bound volume. It is very possible there may be another special issue in that bound volume. All those bib records would be tied to the one volume on the shelf with the one bar code. Presently, I do not assign a bar code to the analytic records. It would be nice to assign the same one to all and then our users could see if the special issue was on the shelf or not. Now they have to do another search on the title of the journal and check there. When there is such a parent-child relationship between items it is possible to use the same barcode for multiple bibliographic records.

They must be unique to the item they identify. If you must use, or are using a numeric only barcode symbology, then you should set different numeric prefixes to the ranges of numbers that you will use on the barcodes for different holding branches or libraries.

My .02 on having Koha accept two same barcodes - bad pie! That's one of the things I intentionally checked for when I installed. Perhaps there's a way to do a feature so that folks that don't want barcodes can shut it off, but I shudder to think at the possible multiple barcode errors that might haunt me later. I know it will catch multiple borrower ids in its own comma'd way, and I know that it used to yell at me when I used the same barcode, which I liked. As far as what you might be able to do about your branches - talk to your vendor and consortium about adding initial digits to distinguish between the branch and the main library. There might be a way to cleverly do this retrospectively. I know that there was a good old function key programmed at my old library, and I usually keep the 304540000 part of my barcode in a notepad file for ease of cutting and pasting. I can't think of any ILS off of the top of my head that wouldn't have the barcode function also as an identifier. Brooke @ Hinsdale
