The Library History Round Table of the American Library Association (ALA) sponsors the biennial Phyllis Dain Library History Dissertation Award. The award is offered only in odd-numbered years. The award, named in honor of a library historian widely known as a supportive advisor and mentor as well as a rigorous scholar and thinker, recognizes outstanding dissertations in English in the general area of library history. Five hundred dollars and a certificate are given for a selected dissertation that embodies original research on a significant topic relating to the history of libraries during any period, in any region of the world.
