{"value"=>"<p>Letters congratulating Lydenberg on his appointment as director; and incoming and outgoing correspondence and internal memoranda to and from Lydenberg and other NYPL staff members, pertaining to acquisitions, cataloging procedures, exhibitions, and similar library-related matters. Only a small portion of Lydenberg's 1934-1941 director's correspondence has survived, chiefly alphabetical files from Th to Z. (Some additional correspondence from these years can be found in the Lydenberg, Hopper and Beals General Correspondence, 1934-1954, also held by NYPL Archives.) Of note in Series I are materials from the survey committee of a user study of Westchester County libraries, on which Lydenberg served (Box 2, folders 2-5); correspondence with the historian Mary Beard concerning the proposed World Center for Women's Archives and the possible placement of the Center with The New York Public Library (Box 2, folder 15); and letters to and from the Yale University Library staff about a variety of matters (Box 2, folders 20-22).</p>"}
