Series I. Office Files, 1921-1937, firms of Arthur C. Holden & Associates, 1920-1930 and Holden, McLaughlin & Associates, 1930-1953 [series]:
Boxes 1-5 may have originally consisted of a separate series for Housing, Leonard Cox and John T. Boyd, Jr., papers. However, it was impossible to reconstruct those series. Wherever possible the original heading is indicated on the folder, and it is filed under that heading, except for place names which are alphabetically filed. The office files include correspondence, articles, book drafts, published material and notes.
Financial records (Boxes 5-7) contain income tax information, bills rendered and paid, certificates rendered and paid, cost sheets and unidentified material.
