Schools with a current SCIS subscription to Authorities can choose to download and import the MARC21 SCIS Subject, Author, or Series authority files, either in Full or Reference only format. Using the full import of Subject headings will import approximately 150,000 subject headings plus related see and see also references. The average school uses between 10,000 and 20,000 subject headings in their bibliographic catalogue records which means that if you import the SCIS subject authority file your subject authority file will contain 120,000+ unused subject headings. This does not cause any problems and is rather a statement of fact. SCIS recommend using the Reference only files for import as this imports the most commonly used subject headings and is therefore more useful as well as delivering a substantially smaller number of headings.
Note: Importing all subject headings, may result in "blind" see also references depending on the depth of your current catalogue records. A "blind" See Also reference occurs when a subject heading has a See Also reference, which, when navigated from and OPAC, results in no items being located because no items have been catalogued with that subject. If you have blind See Also subjects you can either remove them manually or assign them to suitable items in your catalogue.
