[From an email to Clinton Nieweg paraphrased here with permission]

Tim Sestrick reports that he has finished a guide to reference and scholarly resources in percussion. It's on the University of Buffalo music library website, at:
http://ublib.buffalo.edu/libraries/units/music/pathfinders/percussion/guide.html

Much of the content is intended to help library users find percussion resources, mostly literature on music, although it also serves as a bibliography of percussion resources here at UB.
