Moving away from Aleph to a Library Services Platform requires preparation BEFORE data migration. One important pre-migration goal is to separate print items and electronic items out at the title level.
Aleph, like many legacy ILS systems, handles electronic and print records using the same data structures. We have bibliographic, holdings and print records.
In a Library Services Platform, electronic records are handled in a very different way. The data structures are different, as they look to manage these records in a more sophisticated way. For example, the link resolver is taken into account. This requires that the current record structures must be transformed at the time of migration.
There are a number of titles in CUNY’s Aleph catalog which have both print and electronic items on the same bibliographic record. In some cases physical items are incorrectly identified as electronic records. At least some electronic records incorrectly identified as physical print items. There are also physical print items where the library also has access to full electronic text.
As part of your preparation, we are looking to separate print items from electronic items at the Bibliographic level. One of the main reasons is that we need to migrate there records in a very different way. This impacts more than the catalog records. Some titles have serial subscriptions. Both serials patterns as well as acquisitions orders are impacted.
As we look to other libraries that have successfully migrated we find a repeated recommendation. Separate your print items from electronic items before migration. It absolutely requires a great deal more manual work to sort out and rebuild your catalog records if a library does not. For example, under certain conditions electronic items can show up “as if” they are physical items, which is a problem.
A second reason is that print and electronic records can have separate OCLC numbers. OCLC numbers become increasingly important in an LSP environment as the primary match point. This will facilitate functionality such as replicating the CLICS borrowing that we currently enjoy.
There are a variety of problems that arise by not separating these records. This goes beyond not following modern RDA standards. In presentation after presentation libraries keep pointing out the need to get this done. Let’s please learn from their history and not repeat their mistakes.
We will be talking more about this during the coming year in the Cataloging and Acquisitions Committee meetings. (Both areas will be impacted, in their own ways.)
