[Koha-devel] How to indicate the item type (book, CD, CBT, cassette)

Hello! Before converting over from EXCEL to MARC format for import into KOHA, I need to find out how to assign the item type to the MARC record. What fields are item type and how do you specify "book" or "serial" or "CD" etc. Thanks for any help! David W. Hartman Global Business Technology Strategy Library
