Manuscript Level:  Source

Definition:  Source(s) of the information input into the database.

Comment:  Not intended for end-use display, but for in-house verification, should different/contradictory information turn up at a later date; usually very brief; no need to cite personal observation if the matters observed are easily verifiable (e.g. if the inputter has also actually measured the book block, there's no need to cite that, since presumably anyone else re-measuring would come up with essentially the same numbers).

Example:

• in-house files
• notes of Prof. J. W. Smith
• de Ricci; Bond and Faye corrections
• J. Fohlen description

Properties:  Data type: text. Field size: 100 characters.

Required?:  No.
