The first 6 series consist of materials, grouped by
topic or type, that span much or all of McCloy's public career:
Personal Affairs, Diaries, Scrapbooks, Speeches, Awards, and
Photographs. The next 25 series consist of "working papers,"
divided according to McCloy's various positions, roles, and areas
of influence. Series 32 consists of printed material of a
general nature. (Printed material related to a given position is
included in the relevant series.) Series 33: Correspondence and
Series 34: Retrospectives contain unofficial correspondence and
biographical material, which arrived as part of the second
installment to the Papers.
Each series has its own description, which includes
information about the position or role covered by the series, a
detailed description of the material in the series and its
arrangement, and a box/folder listing.
