The Paul Harder collection consists of scores and parts for a variety of chamber music combinations as well as band, chamber orchestra and orchestra works. Those labeled “transparencies” are original copies on onionskin paper, which were used to make reproductions. Any item marked “reproduction” is copied from the transparency by the diazo (or ozalid) process. A few items are original manuscripts, on music manuscript paper. If the individual who prepared the manuscript is known, that information is noted. Two pieces are compositions by his students. One copy of a book prepared for Michigan State University music theory students is included.
