The online presentation of the Miller Flute Collection in the Music Division of the Library of Congress has images of over 1,500 instruments, as well as a 17th-century flageolet tutorial. There is also an impressive array of "Special Presentations", which vary from an explanation what constitutes a flute, in "Flute Misnomers" and "Fife vs. Band Flute" to "Books, Tutors and Patents", which has a link to the images of the book "The Pleasant Companion: Or New Lessons and Instructions for the Flagelet". In the "Understanding the Collection" section of the homepage, there is the "Catalog of the Wind Instruments in the Dayton C. Miller Collection", which helpfully offers "Conventions and Definitions", "Transverse Flute Elements Named in This Catalog" and "Key and Key Mounting Nomenclature" to help researchers and the public better understand the materials available in this great collection. The "Collection Connections" link, also in "Understanding the Collection", is a resource for teachers that, among other things, names the historical eras that are represented in the flute collection, and provides links to "Related Collections and Exhibits" on the American Memory website.
