Collins Library uses the Library of Congress classification scheme to organize books on the shelves. Follow these tips to find the book you need.
Example:

- Start with the top line. It is in alphabetical order. Ex. DC
- The second line is a whole number. Ex. 731
- The third line is a combination of a letter and numbers. Read the letter alphabetically. Read the number as a decimal, eg. Y.23, Y.34, Y.344, Y.4, etc. Ex. .W5513 (*Some call numbers have more than one combination letter-number line.)
- The last line is the year the book was published. Read in chronological order. Ex. 2001, 2005, 2010, 2015, etc. Ex. 1997
Use the library map to find where the book is located.
