At a library, archive, or specialty collection, you handle the work that creates and maintains catalog records — describing items, applying subject headings, assigning call numbers, entering data into the catalog so users can find what the institution holds.
This role lives in bibliographic detail — MARC records, RDA cataloging rules, subject-heading lists (LCSH, MeSH), and the classification schemes (LCC, DDC, NLM) that organize materials. Most cataloging assistants work copy cataloging (adapting existing records from OCLC or vendor sources) with occasional original work for items lacking pre-existing records. Cataloging accuracy and per-item processing time are the operating measures.
What surprises people new to cataloging is how interpretive descriptive work is — many items don't fit cleanly into existing categories, and the cataloger applies judgment that affects discoverability for users years into the future. Variance is wide: at large academic or research libraries the work specializes; at public or smaller libraries it tilts toward generalist work.
Folks who do well in cataloging often enjoy the puzzle of describing items consistently within complex rule systems. LSSC credentials, OCLC training, and increasing fluency with linked-data approaches (BIBFRAME) anchor advancement. The trade-off is the contracting employment field as vendor cataloging and AI-assisted approaches reduce the original-cataloging workforce.
