What constitutes a “new” book?
We know a new book when we see one. But when it comes time to automate the process, we have to define new items in terms of a database query. To be included in the New Books List an item must meet one of the following two sets of criteria: • It must have an item record create date within the specified time span and either a holdings record create date or a holdings record update date within the same time span. This is the criteria for physical items. • It must have a holdings record create date within the specified time span. That holdings record must also have a URL link (i.e. 856) and must not have an attached item record. This is the criteria for electronic-only items. Excluded from the list are certain formats. For example, periodicals are excluded from the physical items criteria to avoid retrieving old, but recently bound journals. Also excluded are items suppressed in the OPAC. The SQL queries that define the criteria may be examined in the newBooks.pl extraction script.
