Organizing and Storing Patterns

The following is the recommended process for preserving tissue patterns. The process is simple and unscientific, but workable until such time as serious conservation and preservations can be accomplished. Dating the Pattern:

Dating the Pattern:
* Copyright dates may be used to date patterns. Do not use patent dates. Note: McCall's included copyright dates on the envelope from the mid 1920s; Simplicity occasionally placed a copyright date on the instruction sheet in the early 1940s and on all instruction sheets from the late 1940s through 1959, then none though 1964. Dates have appeared on the Simplicity envelope since 1965. Vogue occasionally listed the copyright date on the envelope in the 1940s & 1950s.
* Write the confirmed date in pencil on an unobtrusive corner of the envelope.

Store the pattern in clear inert plastic bags.
* Options:
1.Mylar bags such as those sold for storing comic books
2.Food storage bags: regular, open top. Do not seal the bag tightly to allow air circulation inside the bag.

Assigning Archival Numbers:
* If the date of the pattern is confirmed put the archival number on the storage bag for the pattern. Narrow self-adhering labels work well.
* Place the tape with the Archival Number at the top on the outside of the plastic sleeve in a position that will not obscure the Pattern Number.

Storing Patterns
* Filing cabinets in a climate-controlled space make good storage for a large number of patterns. They will fit in two rows to a drawer. A simple divider such as a file folder separates the rows.
* File the patterns by year in numerical order by company.

ARCHIVAL NUMBERING SYSTEM
The archival number has three segments, each separated by a period:
1. The date of issue of the pattern; four digits.
2. The sequential number within the date of issue year that the pattern is catalogued.
3. A letter code to identify the holding collection based on the Online Computer Library Center, OCLC, designation system used for holdings of library abstracts is recommended as designating master location. The key to this designation is available at most libraries. For private collectors, use the owner`s initials.

For example, 1934.3.URI specifies a 1934 pattern, third of that year to be assigned a number, with the original pattern located at the University of Rhode Island. 1934.69.URI designates the sixty-ninth pattern from 1934 to be assigned an Archival Number.
