Hello! We just installed Koha for testing and I'm having trouble orienting myself. I'm the cataloger for Questia, an online library. After a brief, frustrating flirtation with the Green one, I am really enjoying how neatly Koha fits with my current workflow. We will be using Koha to store MARC records that I catalog. None of it is customer facing. Our Koha will feed some data into the Questia system (subject headings and publisher info), so I need to be able to point the data guys to the right tables. I've been using SIRSI a long time (the clients had to be installed on OS/2 machines). Since then, wherever I went, there it was. After importing some records I fired up Brio to see where all the data lived, expecting to find some variation of the SIRSI catalog/marc0/item/callnum structure. After fleeing Brio I looked at the tables in SchemaSpy. Does the MARC data really live in the marc field of the biblioitem table? I tried to look at this in Brio, but it said I couldn't request a binary datatype. I currently do a lot of data checking in the marc0 table. I was hoping to find an equivalent table in Koha. Can anyone help a recovering SIRSI user? I need to wrap my head around how the MARC data is stored. Thanks, Lezlie
