John Cowan <email@example.com> wrote that he will be posting statistics
on the use of accented letters in Library of Congress cataloging data in
the USMARC format, including

Unicode mappings for the USMARC character sets are posted at the Library of
Congress' Web site as
> USMARC to UNIVERSAL CHARACTER SET MAPPINGS
Note that mappings for some character sets (e.g., Arabic) are not yet
finalized, as indicated by the note "See Appendix 2 for Options".
(For location of Appendix 2, see below).
The coding in the USMARC character sets is based on ASCII. EBDIC values
for the upper range of Latin script characters (ANSEL) vary between library
systems using EBCDIC. The information that John Cowan will be posting
describes the Library of Congress practice.
