Finished scanning Folder 4.

Added "19uu" to DPLA date field for undated materials.
When only there's only a year specified, is simply "1921" correct for both date fields?

Added full names to the titles of multi-page documents as suggested (i.e. "Indian Legends of the Pacific Northwest, p. 2" instead of just "p. 2").
