Chris,
This helps a lot. Let me just make sure I have it. A biblio is the general
information about a publication, a biblioitem is a type of incarnation of a
publication (book on tape, paperback, hardcover, first edition, etc.) and an
item is an actual thing that can be checked out that fits one of those types.
So you can obviously have multiple types, and then one or more instances of each
type. That makes sense. Thanks.
Now, during the import process of a bunch of USMARC records using
bulkmarcimport.pl, should I expect my database to be populated with any items?
After doing it, it seems that I get biblios and biblioitems, but no actual
items. Just for fun I created a test "item" that matched one of my biblios and
biblioitems, and then searched for it. It worked great an I got all the
relevant info (bar code, etc). However, it is the only item in my whole
database. ;-(
I guess the real question is, "Is there enough information in a USMARC record to
generate the item as well as the biblio and biblioitems, and should I expect
bulkmarcimport.pl to do that?" I'd like to extract as much information as
possible out of the Winnebago data. Basically, as far as I know, each USMARC
record in the file represents an actual item in our library. Here is a small
piece of the data file (about 4 or 5 records) if that helps clarify anything.
Thanks again to everyone for your help and great work.
FYI, We are hosting a 3 day Linux/Open Source seminar here at the school at the
end of July and I'm giving one session on installing and configuring Koha. It
is aimed at schools and libraries here in Maine. Should be fun. There's a
little more info here if you're interested http://network.gouldacademy.org/
Thanks again. -Derek
