Source Note for Maps Removed from Atlases
(From/Appears in)

From
Many single-sheet maps housed in the Map Department were originally published as plates bound in another work, usually an atlas. If the original work from which the map was removed can be indentified with a high degree of certainly, this information should be added to the bibliographic description. The cataloger must use extreme caution when making this determination, as a given map may have been published both as a single sheet and as a part of an atlas.
The term From is used when describing the source of the item only when the map is identical with a plate in an atlas of other work and there is physical evidence that the item was removed from another publication (e.g., a plate number, folds, backing, text on verso, map printed on two sheets joined, etc.). If there is any doubt as to whether a map has been detached from an atlas, use Appears in instead.
When constructing the 500 note, use the possessive form of the entry element when citing the work from which an item is removed, and include the full imprint information (if known) and date of publication (if known). One method to find this information is to search Orbis for the author/title of the original atlas (if located at Yale).
Example
‡a From Dudley’s Dell’arcano del mare. In Firenze : Nella stamperia di Francesco Onofri, 1646-47.
Also make an added name/title entry for the cited title:
‡a Dudley, Robert, ‡c Sir, ‡d 1574-1649. ‡t Dell’arcano del mare.
Appears In
Use the term Appears in to describe an item that is identical with a plate in a specific atlas or other work, but which exhibits no physical evidence (e.g., a plate number, folds, backing, text on verso, map printed on two sheets joined, etc.) of having been removed from another work.
The phrase is also used to describe an item that is identical with a plate that appears in several different editions of an atlas or in several different works. This phrase is used even if there is physical evidence that the item has been removed since it is usually impossible to determine which of the different editions of works originally contained the item. Variance between the date of the item and the publication date of the atlas should not affect the decision of whether to add the note.
When constructing the 500 note, use the possessive form of the entry element when citing the work from which an item is removed, and include only an abbreviated title of the work. If the main entry of the item differs from the main entry of the work from which it is removed, include the full name in the 500 note. When an item is found in multiple editions of a work, always cite the earliest edition that contains the plate.
