Summary: Instructions for handling laid-in material, by both CMS and SPC staff.
Laid-in material refers to ephemeral items left in resources by booksellers, former owners, etc. Some laid-in material may warrant some detailed description by catalogers (see below), but in general, this isn't necessary.
Catalogers
CMS staff should use their judgment in determining whether laid-in materials are significant or relevant enough to warrant detailed description. For instance, materials like bookstore bookmarks, advertisements or coupons, etc., would not require description in a 561 note.
Insert laid-in material flag (for all cases of laid-in material)
For materials requiring further description:
Insert field 561
Enter a free text note describing the item and its significance
Include $5 MiEM at the end.
Use multiple 561s with $3 at the beginning of each field if you need to provide in-depth description of several pieces of laid-in material.
Example:
$3 Letter. $a Letter written by author to owner containing information about the first draft ...
$3 Photocopy. $a 5 pages of photocopied material from the author's first draft, including ...
If deemed useful for discovery and retrieval:
Add any 655 fields with genre/form terms relating to laid-in material
Add any 7xx fields relating to persons or bodies associated with laid-in material
SPC staff
Insert field 590 with MSS 466 and accompanied by appropriate box number
Retain any 561 and 655 fields created by CMS staff
