The /Classification and Shelflisting Manual/ (CSM) contains the policies
on assigning LC classification numbers and LC book numbers (i.e.,
shelflisting).  Originally written in the 1980s and last updated in
2010, the CSM reflects the AACR2 environment.

The U.S. national libraries’ decision to implement /Resource Description
and Access/ (RDA) led the Policy and Standards Division (PSD) to review
the CSM and determine which instruction sheets needed to be revised to
reflect RDA instructions.  Generally, the text was updated to ensure
consistency with past classification and shelflisting practice, and new
examples were chosen.

Specialists in PSD also took this opportunity to reevaluate some
long-standing practices both to simplify them and to make them more
sustainable in today’s linked, global, environment.

The priority was to first revise the instruction sheets that are most
heavily affected by the implementation of RDA. Those sheets are now
provided as PDFs on the ABA website at
http://www.loc.gov/catdir/cpso/csm_instruction_sheets.html.  PSD will
also post additional instruction sheets there as the revisions are
completed.

The brief descriptions of significant policy changes provided below are
intended for guidance only.  The full instruction sheets should be
consulted for instructions and examples.

/F 175               Editions/

        The instructions for classifying simultaneously published
editions were clarified. **

/F 632               Literary Authors/

        Individual literary authors born before 1925 and anonymous
literary works published before 1925 must now be printed in the schedule
(i.e., numbers must be proposed for them). The cutoff dates had been
1870 and 1899, respectively.

        A section was added to clarify the classification of criticism
and commentaries about an individual author’s works.

/F 633               Literary Authors: Subarrangement of Works/

        Compilations are no longer classified either as collections or as
separate works based on whether the author is still living.  Instead,
the assignment of an RDA conventional collective title is now the sole
determinant.

        The caption *Selections*, which is used frequently in the
literary author tables, will be revised to *Selections. Extracts.
Passages* in order to clarify the distinction between *Selected works*
and *Selections*.

/F 634               Literary Collections/

        The treatment of a literary collection versus a collection in
which one of the works is predominant was clarified.

//

/G 140              Dates/

        The examples of date formats were updated to reflect RDA
instructions.

        Policy on the use of work letters was revised.  New editions of
works entered under corporate body should be assigned work letters
beginning with *b *if necessary, to distinguish between editions
published in the same year.  This change makes the policy for corporate
bodies consistent with the policy for works entered under a personal
name or title. [The instruction to use the workmark *a* for serials was
not changed.]

/G 150              Translations/

        Several languages were added to the Translation Table.

        Polyglot was redefined to mean that there are two or more
translations present within a resource (previously, three translations
were necessary).

        The Cuttering practice for translations in which the language is
not listed in the Translation Table was revised. Instead of repurposing
a Cutter extension in the Table, the language should be assigned a
unique Cutter extension.
