The third article in this issue is devoted to the struggle for the
preservation of New York City's architectural heritage to which
both Isaiah Rogers and Alexander Jackson Davis contributed.
The author of this article, Alan Burnham, is Executive Director
of the Landmarks Preservation Commission of New York. It is
fitting to mention that this position was first held by a former
Avery Librarian, James Grote Van Derpool. It is to the preser¬
vation of our architectural heritage that Avery Library likewise
remains dedicated; and if—unhappily—not all of New York's
notable old buildings could be preserved, at least as much of their
documentation as possible would always find a worthy archive
at Columbia.
