Year/Number Call Numbers
(Approved for use January 10, 2000)


The books and serials in the Beinecke Library General Collection are assigned call numbers in numerical order as cataloged. Call numbers consist of  the location ("Beinecke Library"), the year of cataloging, and consecutive number; they are divided into three groups: octavo, quarto, and folio.


For materials with year/number call numbers, the boundaries for each size are:

up to 25 cm. high (and gaylords slightly over 25 cm. high)
up to 23 cm. wide (and gaylords slightly over 24 cm. wide)
between 25 and 37 cm. high
over 23 and up to 31 cm. wide
over 37 cm. high
over 31 cm. wide
Call numbers should be written following these guidelines:
  1. Mark on Yale bookplate when there is one, generally in the upper left corner
  2. Mark on back cover, lower right hand corner, when there is no Yale bookplate unless cover is too dark
  3. Mark on last page, lower right hand corner, when 1 or 2 don't apply

    The lower left hand corner is the alternate location when the lower right hand corner is unusable.


Call numbers should be reserved in the appropriate call number "dummy" record. All of these call number records can be retrieved by performing the Staff Name Headings search: Yale University Library Rare Book Team. Alternatively, individual call number records can be retrieved using a title search (e.g. Octavo call). Instructions for reserving call numbers are found within each record.

The location code is the code for the collection that owns the material  (e.g. beinwa or beinycal, etc.). For information on the form for inputting into Orbis see the call numbers document.
