How to Find a Library of Congress Call Number

Most works in the library's collections are shelved by Library of Congress classification. The most common location is General Stacks, for which:

  • call numbers A through QA are on library's upper floor
  • call numbers QB through ZZ are on the library's main floor
  • view library map

Sample call number: PR6015 .A33 W57 2001

PR    Read in alphabetical order: PR files before PS
6015    Read in numerical order as a whole number:  6015 files before 6016
.A33    Read the letter in alphabetical order, and read the number as a decimal:
.A33 files before .A4
W57    If there's another letter/number combination, read that number as a decimal even though the decimal point is omitted: W57 files before W6
2001    If there's a publication date, read it in numerical order
