The catalog's main search box searches within all the categories and subcategories listed in the "Narrow by collection" section below it, and only within that set of records. In other words, before a record can be found in the catalog, it must be assigned to a "collection" of catalog records. In most cases, the assignment is done by machine, based on standard coding within the record's MARC data. "Subscription databases" is the exception. There is no machine-readable MARC code for them, so catalogers need to add the abbreviation "DB" to a non-displaying field by hand.

Collection tree

The list of categories and subcategories within a Category:TIND ILS catalog is known as the "Collection tree." Each branch on the tree uses a customizable search query that automatically pulls records into that collection. In most cases, the query is a Regular Expression that searches coded data in the MARC record. For a more user-friendly explanation of the contents of each collection than what's given here, follow the link for each collection's name.
