Hi everyone,

I am new to Koha and to the new MARC21 format.

I am currently using version 2.27 but have some questions.

How does Koha differentiate Library items when they are either a book, audio/visual, Periodicals (serials) or volumes?

I also noticed that the current MARC structure of Koha does not have fields 001-007.

Your help would be greatly appreciated.

Thanks.
