The Miniature Collection consists of items that are up to 10 cm in height and width. All titles are shelved at LSF and classed in Year/Number except those items not eligible for LSF according to the LSF criteria (e.g., custom housing and size); these shelve at 121 Wall Street and are classed in Zm. The general cataloging policies for monographs are followed. 


The size boundaries are:

Up to 10 cm in height and width


The following guidelines are used when marking volumes.

  1. Mark on Yale bookplate when there is one, generally in the upper left corner.
  2. Mark on verso of last page, lower right hand corner, if there is no Yale bookplate. The lower left hand corner is the alternate location when the lower right hand corner is unusable.
  3. If the last page is unmarkable (e.g. too dark or shiny or filled with text or illustrations), mark the verso of the first usable page from the end.

Note: Do not mark call number on original wrappers.


All miniature items going to LSF will be properly housed in the smallest 4-flap enclosures (18.5 x 15 cm) prior to cataloging. Miniature items may have temporary housing as items move from Acquisitions to Cataloging. Always use single barcode labels on either on the housing or use piggyback barcode labels on accompanying blue flags.

Items requiring custom housing and, thus, shelved at 121 Wall Street will be routed to ACCU/Collections Control for housing.


  • Unless instructed otherwise, miniature playing cards are not classed as miniatures. Please refer to the documentation for Playing Cards.

  • For items shelving at 121 Wall Street call numbers for miniature items consist of “Zm” followed by a sequential number. Perform a “Local Call Number” search under “Zm” to find the next available number.

  • For items shelving at LSF, call numbers follow the year/number classification for octavo sized materials

  • The location code is the code for the collection that owns the material. For example, a miniature by Ezra Pound would class in Zm and have the location code beinycal.

  • Serials.

    • For items shelving at 121 Wall Street, the second line serves to keep entries in alphabetical order. To accomplish this, use an arbitrary number between Z5-9. Two or more figures are used.

    • For items shelving at LSF, call numbers follow the year/number classification for octavo sized serial materials.

Past classification practice

  • Prior to April 2017, call numbers consisted of “Zm” followed by the main entry’s cutter number (derived from C.A. Cutter’s three-figure author table). Numbers were expanded to four or even five digits if necessary to distinguish authors and to place them correctly in alphabetical sequence.
  • Subsequent editions were classed by adjusting the cutter, although the addition of lower case letters at the end of the cutter (b, c, d, etc.) were sometimes used.
