Penn State University Libraries uses "Library of Congress" call numbers.
Call numbers appear differently on the book spine and on the online catalog screen.
Multi-line call numbers on books
Call numbers as they appear in the CAT - single line
The following call numbers are arranged correctly as they would appear on the shelf.
- The first line of a call number is filed alphabetically and then as a whole number. (Look for B230 in the hundreds, and B2342 in the thousands.)
- The second line is filed alphabetically and then as decimals (think of .C4 as .C40)
- If the second line consists of a number only, it is filed as a decimal after the letters.
- Dates are filed chronologically after all previous parts are in order. (QD586.8 1996 is filed before QD586.8 1998.)
