Decades after its initial publication and after having been out of print for too many years, it's great to see Howard Mayer Brown's bibliography on instrumental back in circulation. This highly- respected resource is of continuing use to any scholar interested in instrumental music of the renaissance. The sheer number of entries and the detail of their citations makes this source an easy to use and never-ending aid to those who need to check a detail quickly, those who want to compile more specific bibliographies of renaissance music, or even those early music performers seeking new repertoire. Aside from Daniel Heartz' bibliography of music published by Pierre Attaingnant which includes both vocal and instrumental music, few secondary sources provide as much information for renaissance scholars and performers alike. With its re-release, users no longer have to stay in the library to consult this valuable source.
