The Roberts Library uses the Library of Congress classification system to arrange books on our shelves.

The first two lines describe the subject of the book.  The third line often represents the author's last name. The last line represents the date of publication.

 

Tips for Finding Books on the Shelf

Call number 'LB 2395 .C65 1991' on the spine of a book and in the online catalog

Read call numbers line by line.

LB
Read the first line in alphabetical order:
A, B, BF, C, D... L, LA, LB, LC, M, ML...

2395
Read the second line as a whole number:
1, 2, 3, 45, 100, 101, 1000, 2000, 2430...

.C65
The third line is a combination of a letter and numbers. Read the letter alphabetically. Read the number as a decimal, eg:
.C65 = .65 .C724 = .724
