TVT sues Def Jam: transcript of Lyor’s testimony, 2002

The Adler Archive includes letters, documents, manuscripts, images, magazine and newspaper articles, books, sound and video recordings, and other ephemera documenting the history of hip hop. At the core of the Archive are files on more than 1400 hip hop artists and groups from the 1970s to the present. The files include press clippings, promotional head shots, record label press releases, promotional flyers and other ephemera.

The Adler Collection formed the basis for much of the illustrated content in the popular book Def Jam recordings: The first 25 years of the last great record label (2011).
