This portion of the Erlanger papers consists of files of correspondence, lecture notes, and other material, 1910-circa 1940, received by the Medical Library on June 7, 1963. They are contained in boxes 1 through 13, with folders consecutively numbered 1 through 154. Although identified by the library staff as one series, it appears in retrospect to contain several imperfectly ordered series or subseries. For example, the files in Box 1, Folder 1 through Box 4, Folder 56, with contents concerning a variety of issues, have an alphabetical arrangement. They are followed by another group with varied contents, Box 4, Folder 57 through Box 7, Folder 101. Here too the arrangement is basically alphabetical. Files in Box 8, Folder 103 through Box 8, Folder 110 pertain mainly to lectures which JE gave at out-of-town venues. Files on professional and scientific societies and research with which JE was concerned follow in Box 9, Folder 111 through Box 10, Folder 133. There is no discernable arrangement system. The series concludes with files of mainly personal correspondence, again with no discernable arrangement system in Box 13, Folder 134 through Box 13, Folder 154. The exact significance of the cryptic notations A1, B2, C3, etc. is not known. The series has been microfilmed, 35 mm reels 1-10.
