LC exceptions

Added Entries for MIT Names

Upon request, make an added entry for any prominently-named person with an obvious MIT affiliation, regardless of whether the added entry is warranted by the rules. Do, however, follow the rules in citing the name in a note. Do not do any special searching for such an affiliation.

Bibliographies/Z Classification

Whenever there is a choice between classing a bibliography in the Z class or in a subject-specific class, MIT classes the bibliography in the subject-specific class. However, when cataloging with copy, if only a Z class number is available on the copy, use the Z class number.

For example, if this call number occurs on an OCLC record:
050 00 Z6028 |b .W67 |a GA300

Choose the following call number instead:
090 bb GA300 |b .W67

This LC exception applies to these classification ranges:

• Z5060-Z6559
• Z6651-Z6915
• Z6972-Z9999

Classification: PZ1-PZ4

Do not use the class range PZ1-PZ4; instead class as literature. Accept class ranges PZ5-

Note: This policy is still in place, although there are 50+ titles in the MIT catalog in this class range. These are mostly from OCLC recon projects. Some contain a “trailing x” in the call number, which is used to indicate DDC recon call numbers, but some do not.

Exhibition Catalogs for MIT Museums

Class all exhibition catalogs for the MIT List Visual Arts Center and, retrospectively, the Hayden Gallery, with the call number N528.A3. Do not add the year of the exhibition.

Later Editions

We no longer treat later editions as an LC exception. If LC's classification varies from previous editions in MIT's catalog, either in class number or cuttering (or both), accept LC's practice. Earlier editions held by MIT will be classed to LC's latest decision only upon request by divisional library.

Microform Reproductions

When MIT has the hard copy, add the microform reproduction to the record for the hard copy, instead of cataloging the reproduction separately. When MIT does not have the hard copy, catalog the reproduction as a reproduction, i.e. follow LC policy.

TR class

Although the TR class schedule appears to be clear enough, there seems to be some inconsistency in LC practice. There is even more inconsistency in MIT practice, due to an added uncertainty, historically, about when to use the Cutter-Sanborn table for individual photographers.

Current MIT practice

TR647: Exhibitions
Accept call numbers on LC copy as they are. Do not use Cutter-Sanborn cutters. Current LC practice is to use two cutters; when determining call number for contributed copy, use two cutters.

TR650-TR679.5: Collections
"Collections" class number by subject should be followed by a single cutter for main entry. For two different works by the same photographer, the cutter should be varied, usually by taking into account the title of the works. This is different from simply distinguishing two works by using a double cutter in TR647.

Background

TR647: Exhibitions

The schedules state that TR647 is where one classes exhibitions of:

"Works of individual photographers. By name of photographer, A-Z. Under each photographer, arrange by date of exhibition."

In other words, one would expect to see:

TR647.L666 1980 AUTHOR: Levitt, Helen.
TITLE: Helen Levitt : color photographs

TR647.L666 1991 AUTHOR: Phillips, Sandra S., 1945-
TITLE: Helen Levitt exhibition catalog

But in fact, for the second title LC assigned a double cutter (in 1991):

TR647.L666.P45 1991 Helen Levitt

And more recently:

TR647.M554.L69 1995 Tina Modotti: photographs

And yet LC's shelflist (in LOCIS) has at least as many instances of single cutters.

TR650-TR679.5: Collections

Because of the proximity of these class numbers to TR647 and past uncertainty concerning the extent of our "LC exception" policy for artistic photographers, there has been much confusion about whether to use double cutters or Cutter Sanborn. Unlike TR647 however, this class is not meant to group works by individual artists per se but rather by subject and main entry.

However, "Collections" should not be construed as necessarily meaning more than one artist, the term is used in the schedules in contrast to exhibitions. This is another source of confusion, as it is not always clear whether a book is an exhibition catalog or not, and even when it is, this distinction in classification may not be clear to catalogers. For example, two books by a single photographer flourishing after 1951 may appear extremely similar, but one could be classed in TR647 and another in TR654.

Because it is not unusual for a photographer (main entry) to have more than one work in TR650-654, there may be a tendency to treat them in the same way as TR647. However, the practice for all works in TR650-TR679.5 should actually be straightforward:

"Collections" class number by subject should be followed by a single cutter for main entry. For two different works by the same photographer, the cutter should be varied, usually by taking into account the title of the works. This is different from simply distinguishing two works by using a double cutter in TR647.

T171: works by and about MIT

For works about MIT, LC used class T171 and the accompanying table, which is very brief. MIT used T171 in combination with the more specific table in the L schedule.

Whenever MIT has already been established under a class number with the cutter .M414, continue to use this cutter. (LC’s author number would vary.)
