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 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 Python 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. Note that the "AND 980:BIB" at the end of each shouldn't be necessary, but was added as a work-around to a miscoding issue at TIND.
Remember: Byte counts start at 0, not at 1, so even though the number in curly brackets looks like the byte reference from MARC 21, it's still just "number of times the previous character appears in the string."
- Books & Serials consists of all records in the following subcategories:
- Incunabula
Query: 000:/^.{6}[ace]./ AND (008:/^.{7}1500./ OR 008:/^.{7}14./) AND 980:BIB
Explanation: All bibliographic records where byte 06 of the MARC Leader is a, c, or e (Type of Record = Language material, Notated music, or Cartographic material) AND where either of these is true: bytes 07-10 of the MARC 008 are "1500" or bytes 07 and 08 are "14" (that is, the year of creation of the original resource is either the year 1500, or any year from the 1400s). Manuscripts incorrectly coded as printed text will appear here if they date from the 1400s. - STC imprints
