In this innovative resource, Thomas P. Walsh has compiled a unique collection of some 1,400 published and unpublished American musical compositions related to the Philippines during the American colonial era from 1898 to 1946. The book reprints a number of hard-to-find song lyrics, making them available to readers for the first time in more than a century. It also provides copyright registration numbers and dates of registration for many published and unpublished songs. Finally, more than 700 notes on particular songs and numerous links provide direct access to bibliographic records or digital copies of sheet music in libraries and collections.
