Anglo American Cataloguing Rules 2

Field-by-Field: Where AACR2 Actually Works and Where It Falls Apart

The basic principle behind cataloguing under AACR2 is straightforward on paper. You look at the chief source of information on the item itself and you record what you see, in the order prescribed by the rules. For a monograph, that usually means the title page. For a sound recording, it's the disc or its label. The rules tell you which fields to use, what punctuation goes between them, and how to decide who or what gets the main entry. That part is mechanical. The hard part is everything in between. I spent years doing this work before RDA replaced it, and the thing nobody warns you about is the sheer volume of edge cases where the rules don't give you a clear answer. AACR2 was built as a massive cross-referencing maze. Chapter 1 through Chapter 21, each with appendices, notes, and overlapping instructions. You learn to navigate it by memorizing the traps, not by reading it cover to cover.

Here is the core workflow, stripped of the official language that makes it sound more complicated than it is. Take a book. Look at the title page. Record the title exactly as it appears in field 245, including the subtitle and any parallel titles. If the title page names a person as author, put that name in field 100. If multiple people are involved, the first gets the main entry; everyone else goes into 700 fields with their relative roles noted. For corporate authors, it is the same logic but with 110 instead of 100. Then you handle the publication statement in field 260. Place, publisher, date. You abbreviate publisher names according to Table T2 in the appendix. You do not guess. If the name does not appear in the table, you use the most common abbreviation, or if that cannot be determined, you leave it unabbreviated. This is where most junior cataloguers make avoidable mistakes. They abbreviate things like "Press" to "P" because they think it looks clean. The table says "Press" becomes "Pr," not "P." Small detail, huge impact on consistency across a catalogue. The physical description in field 300 follows a strict pattern: number of pages or volumes, any illustrations, dimensions. You include the dimensions in centimeters. You note if something is unobtainable by writing "v." without a page count rather than leaving it blank. Blank fields are worse than incomplete ones because they suggest you did not bother to look.

The Specific Problems That Actually Come Up

I ran into a particularly annoying case involving a multi-volume set published by a university press where the title page of volume one listed the editor in a prominent position, but the copyright page listed the series editor separately. AACR2 rule 21.1B says you enter under the main author or corporate body named on the chief source. The question was whether an editor counted as a main entry point. The answer, according to the rules at the time, was no unless the editor was also responsible for the intellectual content of the work as a whole. In this case, the editor had compiled the volume, which meant I had to enter it under the editor using 100, not under the series name. A catalogue built under different interpretations would have split the same work across two author headings, which is a real pain for patrons searching by author. Another recurring issue involves electronic resources. AACR2 was not designed for them. When I processed e-books and online databases in the later years of its use, I had to adapt the rules in ways that were technically violations of the letter of AACR2 but necessary for the material to be findable. The workaround was to treat the URL as a local addition in field 856 and to use the title proper of the resource as the main entry rather than trying to force a corporate authorship that did not exist in any traditional sense. Some libraries handled this differently. Some just stopped cataloguing electronic resources properly and left them as bare records. Both approaches had consequences.

Common Mistakes That Waste Time

The biggest time sink in AACR2 cataloguing is getting the name authority file right. If you enter an author name without checking it against the Library of Congress Name Authority File first, you will create duplicate headings later. I have seen libraries spend hundreds of hours merging duplicates caused by lazy authority work early on. Check the name. Always. Even if it seems obvious. "Smith, John" is not obviously enough. There are dozens of them. A second mistake is inconsistent use of subfields. Field 260 subfield $a is place, $b is publisher, $c is date. Mixing them up or skipping them entirely creates malformed records that break downstream applications. Some systems will accept the record anyway and hide the error until someone tries to sort by publisher or generate a statistics report. By then the damage is spread across thousands of records. A third area where people struggle is with uniform titles. You use uniform titles when a work exists under different titles in different editions or translations. The rule is to add the uniform title in field 130 or as a second element in the main entry field. But you only do this when the variation in title would cause the work to be filed under different headings. Not every translation needs a uniform title. Only the ones where the title changes enough to break the filing sequence. Beginners often add uniform titles unnecessarily, which clutters the record and confuses searching tools that do not expect them.

Where AACR2 Breaks Down Completely

The rules were written for a card catalogue world. They assume a linear, sequential entry process. They assume print materials with stable, clearly identifiable chief sources of information. They do not assume born-digital objects, dynamic content, collaboratively authored works, or multimedia items that blend text, audio, and video. When you encounter these, AACR2 gives you no reliable path forward. You either bend the rules until they snap or you accept that the catalogue record will be incomplete. There is also the problem of labor intensity. A full AACR2 cataloguing record for a complex item can take 45 minutes to an hour for an experienced cataloguer. For a straightforward monograph, maybe 15 minutes. With rapid acquisition cycles and shrinking staffing, that pace is unsustainable. Many libraries moved to copy cataloguing as a primary strategy, which shifted the workload from original cataloguing to quality control of existing records. This is faster but it means your catalogue inherits every error made by the source library. You gain speed and lose independence. The shift to RDA was not just a branding change. It was a structural response to the limitations of AACR2. RDA removed the dependence on physical media, introduced a more flexible entity-relationship model, and allowed cataloguing directly from digital sources. If you are starting out now, you will learn RDA, not AACR2. But understanding AACR2 is still useful because many legacy records in existing library systems were created under it, and the logic behind those records still governs how your catalogue is organized.

If you need to study the rules themselves, the full text of AACR2 was historically available through the Library of Congress and various academic subscriptions. The official online version was maintained at access.library.northwestern.edu/aacr2/index.html before it was archived. There is also a widely used mirror at aacr2.info. Neither is actively maintained, but they serve as references for working with older records or understanding the rationale behind current RDA decisions.
