Find a Book with Library of Congress Call Number
• Most of the books in Rothrock Library are located on the lower level. DVDs, videos, and audiobooks are in LB 109, the Media Periodicals Room, on the upper level.
• Labels on the end of each row of shelves help you find the correct area for a call number.
• The call number is written on a white label on the spine of a book.
• The letters on the first line of the call number are arranged alphabetically.
• First locate the books that have call numbers with the correct first letter (e.g., H).
• Next look for the second letter, if there is one. H comes before HA; HM comes after HJ and before HX.
• These call numbers are in correct order:
• Sometimes the second line of an LC call number has a decimal number.
• Books that have a decimal in the second line, like the third, fourth, and fifth examples below, will be shelved after all the books that have the same classification letter(s) and numbers, but no decimal.
• These call numbers are arranged in the order in which their books would be shelved:
• The third line of a Library of Congress call number begins with a letter.
• The numbers following this letter are considered a decimal when locating a book on the shelf. Therefore, for example, G9 will follow G68 because the 9 in G9 will be filed as .9 and the 68 in G68 will be filed as .68.
• Here is a row of books with LC call numbers, filed in correct order:
