Cataloging Study Guide

📖 Core Concepts Cataloging – creation of machine‑readable metadata (author, title, subject, etc.) that serves as a surrogate for a resource and makes it searchable. Bibliographic control – the set of rules and processes that describe resources so users can reliably locate the right item (identification, description, classification, access points, location). FRBR model – hierarchical entities: Work → Expression → Manifestation → Item; the backbone of modern RDA. Descriptive cataloging – records the physical/form details of a resource (form, title‑page transcription, entry style). Subject cataloging – assigns controlled‑vocabulary terms (e.g., LCSH) that describe what a resource is about; includes classification (DDC, LCC) and indexing. Authority control – a single standardized heading for each person, corporate body, or title to keep records consistent across libraries. Cooperative cataloging – sharing of bibliographic/authority records among libraries to avoid duplicate work. 📌 Must Remember Six Functions of Bibliographic Control (Hagler): Identify existence of resources. Identify works/parts contained. Collect resources in depositories. Produce standard lists (catalogs, finding aids). Provide name, title, subject, other access points. Provide means of locating each copy (call number, OCLC status). Key historical rules: Panizzi’s 91 Rules → Cutter’s 1876 Rules → Lubetzky’s principles → FRBR → RDA (current). Main entry rule – first author listed; if no author, the title becomes the main entry. Added entries – additional authors after the main entry. ISBD eight areas – title & responsibility, edition, material specifics, publication/distribution, physical description, series, notes, standard number. MARC – dominant machine‑readable format since 1966; being superseded by linked‑data models (BIBFRAME). Transliteration – use ALA‑LC Romanization tables to render non‑Latin scripts into a single catalog. 🔄 Key Processes Descriptive Cataloging Workflow Examine the item → transcribe title page → determine form & physical description → choose entry style → encode in MARC/XML. Subject Analysis Workflow Read/skim content → identify core concepts → search controlled vocabulary (LCSH) → select headings → apply subdivision rules → add classification number. Authority Control Creation Locate existing heading in authority file → verify correctness (name, dates) → create or update record → link to all bibliographic records. Cooperative Cataloging Cycle Search shared catalog (OCLC, WorldCat) → import existing record → edit for local holdings → contribute back any enhancements. 🔍 Key Comparisons Descriptive vs. Subject Cataloging Descriptive: focuses on what the item is (form, title, physical traits). Subject: focuses on what the item is about (topics, themes). MARC vs. BIBFRAME MARC: legacy, field‑based, limited for linked data. BIBFRAME: entity‑relationship model, RDF‑compatible, web‑ready. Main entry vs. Added entry Main entry: primary access point (first author or title). Added entry: secondary authors, contributors, or corporate bodies. RDA vs. Anglo‑American Cataloguing Rules (AACR2) RDA: FRBR‑based, user‑task oriented, digital‑friendly. AACR2: rule‑heavy, print‑centric, largely superseded. ⚠️ Common Misunderstandings “Cataloging is just typing data.” – It requires analytical decisions (subject analysis, authority matching) and adherence to standards. “If a work has no author, you leave the author field blank.” – The title becomes the main entry. “MARC is obsolete, ignore it.” – MARC still dominates many collections; understanding its structure is essential for legacy data. “All subjects are free‑text.” – Subject headings must come from controlled vocabularies to ensure consistency and discoverability. 🧠 Mental Models / Intuition “Library as a map” – Think of cataloging as drawing landmarks (author, title) and roads (subject headings, classification) so users can navigate from any point to the item. “FRBR as a family tree” – Work = ancestor, Expression = child, Manifestation = grandchild, Item = great‑grandchild; each level adds concrete detail. “Authority control = a phone directory” – One standardized entry (phone number) for each person ensures you always reach the right individual. 🚩 Exceptions & Edge Cases Anonymous works – Use title as main entry, but also check for corporate author possibilities. Multilingual titles – Include transliterated title and original script if supported by the cataloging rules. Serials vs. monographs – Serial cataloging adds continuation statements and ISSN; monographs use ISBN and fixed‑date publication data. Non‑print materials (e.g., sound recordings, moving images) – Require additional form codes and may use RDA extensions for carrier type. 📍 When to Use Which Choose RDA when cataloging digital or mixed‑media collections, or when FRBR‑based relationships are needed. Use AACR2 only for legacy catalogues that have not migrated; otherwise, transition to RDA. Select MARC for internal library systems that still rely on traditional ILS; use BIBFRAME or RDF when exporting to the semantic web or building linked‑data services. Apply LCSH for most English‑language subject headings; use MeSH, FAST, or local vocabularies for specialized domains. 👀 Patterns to Recognize “Author‑title‑statement” pattern in MARC fields 100/245 indicates main entry vs. title. “Classification number + cutter” pattern shows hierarchical location (e.g., D123 .C45). “FRBR levels in a record” – Look for fields that differentiate Work (title), Expression (language/edition), Manifestation (publisher, format), Item (call number, barcode). Bias cues – Presence of outdated subject terms or gendered language often signals a need for ethical revision. 🗂️ Exam Traps “MARC is no longer used” – Many exam questions still ask for MARC field numbers; answer with the field (e.g., 245 = title). “Main entry always author” – Forgetting the title‑as‑main‑entry rule for anonymous works leads to incorrect answers. “RDA replaces all older rules” – RDA supersedes AACR2 but does not invalidate historic concepts (e.g., “cutter numbers” still appear in classification). “Authority control eliminates all variation” – Authority files standardize headings but still allow variant references (see “see also” links). “Transliteration is optional” – In multilingual catalogs, failing to transliterate will be marked wrong; the correct answer cites ALA‑LC tables.
