In this bulletin, the Music Teachers' National Association committee on the history of music and libraries presents the summaries of the questionnaire prepared by the committee and sent out by the Bureau of Education in 1917-18. This is the first statement to show the condition and resources of the music sections of public and school libraries, containing 5,000 volumes or over, throughout the United States. The result is both encouraging and discouraging. It is encouraging in that the report shows a fairly wide dissemination of considerable music libraries throughout the country, with some collections of first rank. It is encouraging for the reason that many more libraries report increasing interest in the music departments, in comparison to the number where music interest is stationary or decreasing. It is encouraging because many of the librarians who report small collections are careful to note that the reason therefore is recent installation of the section, perhaps even the youth of the library itself, or lack of room or of other facilities. The discouraging feature is the lack of interest shown, though not more frequently than might be expected, by librarians, music teachers, and music lovers. One of the prime objects of the committee is to deal with this matter, and now that the information has been collated, prompt steps will be taken. Appended is "Music in Our Libraries" (excerpts from an article by O. G. Sonneck), and a Bibliography of Music. An index is also included. (Contains 1 note and 6 footnotes.)
