Percepción y variación lingüística : enfoque sociocognitivo / Rocío Caravedo. (OCLC #894227744)

When classifying this title, I assigned the class number P120.V37 (variation in language) followed by a cutter for the main entry (Caravedo). Just following the Cutter table from the Subject Cataloging Manual on Shelflisting, I would have assigned the cutter C37:

  • C as the first letter of Caravedo
  • 3 for the letter a following an initial consonant
  • 7 for expansion, as the next letter r is between p-s

CI browsed Library of Congress’s catalog in the area of P120.V37 C and spotted a similar title with call number P120.V37 C37 1997, with the second cutter based on the main entry Caro. I shifted that cutter slightly for the title in hand, so that it would file correctly, with Caravedo before Caro:

Ionic channels of excitable membranes / Bertil Hille. (OCLC #10755486)

This gift book was already labeled with a call number that didn’t quite look like a Library of Congress call number. It was in the copy we found as a National Library of Medicine call number:

060 __ ǂa QH 601 ǂb H651i 1984

We re-labeled with a Library of Congress call number, which was quite similar:

050 00 ǂa QH601 ǂb .H55 1984

The two classifications are similar enough that in our collection, we do have some titles with NLM call numbers assigned, but interfiled with the LC collections.


What a modern Catholic believes about women / by Sister Albertus Magnus McGrath. (OCLC #324934)

This gift book is already labeled with a call number “SD82 M147”, which is from the Union Theological Seminary classification (SD82 = History of women, matriarchy).

Our library uses Library of Congress classification, so we reclassed as

BV639.W7 M37 1972

BV639.A-Z is The Church and special classes, A-Z, so the first cutter W7 is for “women” and the second cutter “M37” is for McGrath.

I have seen classifications where “Mc” at the beginning of a name is filed as though it were “Mac”, but LCC is not like that. In the Subject Cataloging Manual on Shelflisting, under Filing rules (G 100), Rule 15 (“Names with a Prefix”) says that a prefix that is part of a name or place is treated as a separate word unless it is joined to the rest of the name directly or by an apostrophe (without a space), and should be filed letter by letter, and has as an example filing order:

  Marshall, Catherine, 1914-
  McGrath, Suzanne
  Metal products manufacturing

Otsuchi : moving forward from the Great East Japan Earthquake and Tsunami : a photo essay of a small town in Japan / Meiji Gakuin University Volunteer Center ; editing and design, Cody Rapley. (OCLC #889095202)

Most call numbers in Library of Congress Classification follow a pretty standard pattern: 1-3 capital letters, a number (possibly with a decimal part), one or two cutters, and sometimes a year. One exception is in call numbers for books about events like earthquakes, where the class number also includes a year for the occurrence (in addition to the year that might be in the “item number” part of the call number). For example, HV599 is for general works about earthquakes, but HV600 is for works about specific earthquakes by date, then subarranged by place, A-Z, and by author, A-Z.

This title about the 2011 Tōhoku earthquake and tsunami, so the first cutter is for Tōhoku, the region where that earthquake took place. The second cutter is for the main entry, which in this case is the title. This forms the call number:

HV600 2011 .T64 ǂb O87 2014

Still running : the autobiography of Nate Northington, the first African American football player in the Southeastern Conference / Nathaniel Northington ; with La Monte McNeese. (OCLC #851416833)

Individual biographies in football are classed under GV939.A2-Z. The Classification Web description looks pretty normal, so it is tempting to cutter by the author’s name. Doing so would hide his autobiography under N, between biographies of him written by others. Why not put his first?

Though ClassWeb doesn’t mention it, “Individual Biography” numbers have a specific meaning for A2-A5, which (unless specified) is detailed in the Biography Table; this particular title should have second cutter A3 for Autobiographies, diaries, etc. putting it close to the front, where it belongs.
