[Koha] Need some answers about bar-codes

[doybia at gmavt.net]

I'm part of a group of libraries in Vermont who are in the process of
moving to Koha. Most of the other libraries are already automated, but a
few of us are still on card catalogs, so we are starting from scratch.

Here are the questions:
1)I've moved some of my marc records into Koha, but the bar code generator
in Koha doesn't work for me. Does anyone know what will make this work so
I could print my own?

2)If printing my own won't work, I can afford to go and buy barcodes, but
I need to know if Koha has any specs on barcodes. Will any convenient
variety work, or do I have to do something standard, and if so, what?

3)If I do go and buy barcodes and apply them to my books, how do I link
the barcode to the marc record?

4)How about the barcodes for the patron cards? We'll be importing the
patron records eventually (they are currently in an Excel spreadsheet) and
they'll need to have barcodes attached, too. I assume they should be
different from the book barcodes. At our meeting today I was told to start
the Patron barcodes with P and the Book barcodes with B, which seems
simple enough. Any other suggestions?

Thanks in advance,
Deborah
