This chapter lists books, articles, and chapters devoted to quartets by a single composer. In selected instances, thematic catalogs in separate volumes have been included as well when it was determined that these would be of particular beneﬁt to the researcher, especially in those cases where few other references exist outside of an encyclopedia article and/or when such texts offered useful information about a particular composer and his/her quartets. For an excellent index of thematic catalogs, see Brook, Barry S. and Richard J. Viano. Thematic Catalogues in Music: An Annotated Bibliography. 2nd edition. Stuyvesand, New York: Pendragon Press, 1997. xlviii, 602 pages. ML113.B86.1997. ISBN: 091872886X. Series: Annotated Reference Tools in Music, volume 5.
