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
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 U of M’s Policy No. 1:2A:11:05
on Conflict of Interest/Personal Benefits, U of M’s 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 U of M’s 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.
