Loose (unattached), folded plates, maps and charts, which serve as supplemental material, but do not warrant independent cataloging or separate physical processing will be handled as follows:

At the time of cataloging, all physical pieces will be individually inscribed in pencil with base call no. only (in the upper left corner of the front surface of the folded item) by the cataloging LTA. The inscription will serve primarily as identification to help reconcile the supplementary material with the main volume, if separated. The designation "Suppl." will not be used, as the "Suppl." caption is warranted only for standalone or separately bound items.

The LTA will prepare a blue slip with the appropriate instructional note:

Affix label: POCKET CONTAINS (1) FOLDED MAP [plate, chart, etc.]

Subsequent to the cataloging process, each physical piece will also be property stamped on the folded, front surface, and then placed in a pocket or envelope, inside the back cover of the main volume for safe, permanent retention.

An appropriate contents label will be affixed to the envelope:

e.g. POCKET CONTAINS (1) FOLDED MAP

While the accompanying material will generally be mentioned in the bibliographic description, the plates, etc. will not be shelflisted in NOTIS, and separate cataloging and processing statistics for the supplementary material will not be reported.

Plates or maps which will be shelved independently from the main volume (e.g. a collection of folded maps to be pam bound, shelf listed and labeled separately as a Suppl.), do require more traditional and detailed permanent inscriptions in indelible ink with the designation "Suppl."

Consult the Processing unit supervisor for specific recommendations in handling unusual, non-routine or unfamiliar situations.
