[Koha] Koha's call number vs. our library's call number

[Hans Henderson]

Stephen,

Thanks for answering. 

> I'd recommend you put your call number in 
biblioitems.classification and not mess with dewey (everything should 
still work OK).  Use some sort of unique numbering system for 
barcode.   -- SH

My numbering system is indeed unique, but is unique for every 
item/copy of a title, not for each biblioitem (see my original 
message for the scheme's details). And that number also functions as 
the barcode, which is why I thought that would be a good field. Are 
you saying it's necessary to use a biblioitem field for 
searching/OPAC display purposes? I can see that would make sense, but 
if 2.2 is going to use itemcallnumber, maybe I can use barcode in the 
meantime?

If not, I suppose I could put the first five parts of the number - 
unique to each biblioitem - in the field you suggest, and then put 
the whole call number in the barcode field of the related items. I'd 
just have to remember to change both levels if the number has to 
change.

And I still need to know if it's OK to ignore the Koha call number - 
it might have Dewey in it or it might be empty for a lot of records - 
is that OK?

Thanks,

Hans

>> I've created an alphanumeric local call number unique to each item 
(copy of a title) I'm also using this as a barcode number. the first 
part of the number shows the level, then the set, then the titles, 
and then the individual copies. So Q010A04 means "the fourth copy of 
title A in set 010 at reading difficulty level Q".

>> I plan to put this local call number into Koha's barcode field in 
the items table, and link that field to MARC 852c - please confirm I 
got at least that right, or should I use a 9xx?
