Hi there, I am setting up our test Koha 3.0 and am wondering how Koha 3.0 is designed to handle item types and collections. Turns out we have 3 different ways to solve the same problem! There must be a better way ... *1st method: Adult Non Fiction. (insert a prefix before dewey number in classification field)* These are all purchased from the 1 budget but go into different collections within the Adult Nonfiction: So ItemType= BN and for each of the sub-collections we enter a prefix in the classification classification field: ie Horowhenua Collection: H993.101 or Maori Colletion M572.8 etc). This is good enough but we want to move to breaking our collection up into living rooms or subject categories housed together and wonder if this method will usefully scale upwards. How, for instance, will this translate usefully into the OPAC view? *2nd Method: Fiction (insert a category statement into the classificatoin field)* So they all get item type BF but then in the classifiction field we enter: F-Mystery or F-Romance or F-Western etc. *3rd Method : Junior Fiction (Distinct item types for each subcollection)* ie Junior Castle collection: item type BJC, Junior Kermit Collection: itemtype BJK and the main junior fiction sequence: item type: BJF While we are very very clever being able to manage 3 such different solutions to what is essentially the same problem; it is clearly ridiculous. Learning of any other ways to approach the management subcollections in Koha 3.0 would be greatly appreciated!. Cheers Joann Ransom.
