MIcroforms
Sometimes it is difficult to locate microforms in HOLLIS. Try searching on the name of the holding library in the Creator field, or on the shelf number of the original item as a keyword.
There is an annotated photocopy of the Grove article "Sources, MS. II.5. Western plainchant, 12th century" in the Keeper's desk (bottom drawer) with pencilled-in annotations of Isham call numbers for those items Isham owns in reproduction.
