Microforms
All microforms purchased should meet ANSI standards for the production, processing,
and storage of film as an archival medium.
Before orders are placed or gifts accepted for microformat material, the following
points are considered:
(1) format and size;
(2) reduction ratio/reader availability;
(3) film type;
(4) polarity;
(5) print reproduction capability; and
(6) access tools, i.e. printed indexes, magnetic records.
The chart below specifies present capabilities and preferences for the U of M Libraries.

Authority to make purchases for the library collection is specifically delegated
to the U of M Libraries in U of M Procedure No. 2D:03:05A. The purchasing work of
the Acquisitions Department is all done in accordance with UM Policy No. 1:2A:11:05
on Conflict of Interest/Personal Benefits, UM Procedure No. 2D:03:05A on University
Purchasing Procedures, and Tennessee Board of Regents Policy No. 4:02:10:00 (copies
available in the Information Manual).
All the documents created in this process are public records and are subject to regular
examinations by UM Internal Auditing staff and unannounced audits by State of Tennessee
auditors. The department maintains all necessary files and records to provide acceptable
audit trails for each transaction.
While the department's records are public documents, Acquisitions staff members are
expected to defer questions from auditors, reporters, or other outside persons to
the Head of the Acquisitions Department, Associate Dean, or Dean of Libraries, unless
otherwise instructed by one of these administrators.
Likewise, questions from faculty, students, or outside parties regarding fund allocations,
prices of individual titles ordered, etc., are to be referred to these same administrators.
