==Process==
At present, the process begins by examining each book or periodical for an ISBNor ISSN. This is preferable to using author/title information, as it is more specific. This data is applied to the Z39.50 lookup function of the catalog software to see if a reasonably complete MARC record is available to download. If so, the record is brought in, checked to see that it's a good match (often they are records to a microform version of the work), and the item is added.
The Location field is assigned from the list of those available. If a suitable code is not available (for example, a new country's history), then a new code is created and assigned.
Items for which a record cannot could not be quickly located are were boxed with the label "Hard Books". Items that turn out to be periodicals are Periodicals were boxed with the label "Serials". Both are returned to storage for later processingnow being processed as time permits. Better understanding of both Z39.50 options and original cataloging no longer justify repeat handling.
This is the basic work that needs to be done, but it is not all.
