Guidelines for Uncontrolled Subject Terms (653s) Subject Acess (FAST or 653s)Anchor F F
Starting on July 1, 2019, LTS uses FAST subject headings on class on receipt records in most cases. If the subject access necessary cannot be adequately expressed with FAST terminology, use uncontrolled keywords (653s) as before.
Consult LTS Procedure #127, FAST Headings for Cataloging for guidance on the use of FAST.
If the record for a foreign-language work has been supplied by LC with an informative, keyword-rich 520 in English, do not add FAST or 653s.
Add FAST terms or English words, translated generally from the title, to items without 520s written in foreign languages and to English-language books with titles that do not reflect their subjects. For example, the English title The high road and the low road, which is about bookmobiles, does not reflect the subject of the work, so you would assign a FAST or 653 field.
However, do not apply these instructions to works of the imagination (novels, stories, poetry, plays).
