Based at the Mills Music Library at the University of Wisconsin, the American Sheet Music Collection contains thousands of pieces of sheet music published in the United States before 1900. Many of these items came to the library as gifts, including a significant group of publications that once belonged to composer/publisher Joseph P. Webster. The musical genres included here are impressive, and include airs, folk songs, gallops, hymns, marches, and nocturnes. Visitors can perform a guided search across all of the items, or just search for specific items of note. It's quite interesting to type city names into the search engine as the results may indicate where songs, both well-known and unknown, were published originally. This is an impressive collection and musicologists and others will find much to enjoy here.
