Rules for Classification of Genealogical Sources (929.3)

These rules apply only to items in the North Carolina Collection. They do not apply to Reference or circulating materials.

I. Items to be included in 929.3 are:

  • Everything already placed there by DDC.
  • All cemetery abstracts.
  • All troop rosters. Histories of military units should not be placed in 929.3. However, if an item contains significant entries on individuals who served in the unit, it may be placed in 929.3.
  • All church records consisting primarily of church records (not primarily a history of the church).
  • Some compiled genealogies (not family histories on one or a handful of surnames). The Genealogy Librarian will ordinarily make this determination.
  • Some gazetteers and other items that are of use as finding aids to genealogists. These will only be placed in 929 when explicitly requested by the Genealogy Librarian.

II. Classification and call numbers

A) Classify in 929.3. Do not use the area subdivision in the classification number as called for in DDC. Items in 929.3 will be arranged with geography as the primary division and item form as the secondary division. This is accomplished by the classification scheme described below.

B) Each term of the classification will be as follows:

Term 1: Collection (NC).

Term 2: DDC number (929.3).

Term 3: First geographic subdivision. All items will have a postal code if they pertain to a single state or "AA" if the item pertains to more than one state or the entire country.

Term 4: Second geographic subdivision. Only items pertaining to a single state (with a postal code) will receive a second geographic Term.

Term 4 for items pertaining to a single county will be the name of the county. Items pertaining to the entire state or multiple counties will receive "AAA" as their Term 4. Counties that no longer exist will not be used. They may be placed in AAA or in another county. The appended list of NC counties details which counties these are and how to handle them.

There may be exceptions to the rule placing items pertaining to multiple counties in AAA. If all of the counties can be traced back to a single parent county, the parent county should be used. The Genealogy Librarian should be consulted in cases where this is a question.

Books to consult to resolve questions of county parentage include: The North Carolina Gazetteer by Powell, The Formation of North Carolina Counties, 1663-1943 by Corbitt, and Maps Showing NC Counties and Boundaries 1663-1911 (not catalogued).

The Genealogy Librarian will deal with non-NC counties on an individual basis. In most cases, the county name or AAA will be used, unless there is obvious reason to do otherwise. As we acquire gazetteers for other states this will become easier.

Term 5: Division by form.

Term 6: Standard main entry cutter. A volume/book number may follow the main entry cutter if appropriate.

C) Placement of call numbers on labels

Line 1: Term 1 (NC)

Line 2: Term 2 (929.3) Term 3 (postal code, should be bolded)

Line 3: Term 4 (county or "AAA") Term 5 (decimal for form and, if census, the year)

Line 4: Term 6 (cutter and volume)

Exception: If the item does not pertain to a specific state and is classified as AA, then Term 3 (AA) should be bolded and should appear on line 3 followed by Term5 (item form).
