You don't want to be reverting your imports. The ISBN match is a string match so if the strings in the 020 field match each other then they will match the records. If Safari uses another field for a identifying number you could create a matching rule to use that field instead of the ISBN so that you get more accurate matches. I know that some ebook vendors do that. Nicole On Tue, Feb 21, 2012 at 3:52 PM, Hartman, David W. - GBTS Library <David.W.Hartman@disney.com> wrote:

My library subscribes to Books24x7 and Safari Books online.  When  I update my collection to have the latest book records from these providers, I assume I should REVERT the last batch input and IMPORT the latest records.

If I took an existing Safari biblio record and added a print (second copy) to this existing record, would the print item (second copy) and biblio record disappear when I REVERT the Safari record, or would the biblio and item record remain for the one print copy?

Let me know .. I do not want to start the updating process without understanding its impact to revert and import updates. _______________________________________________ Koha mailing list  http://koha-community.org Koha@lists.katipo.co.nz http://lists.katipo.co.nz/mailman/listinfo/koha
