Call numbers are your path to locating physical books in the library. Call numbers help librarians and library staff organize our materials and they also make it easier to locate books for library users. Our libraries use Library of Congress classification, meaning books are shelved according to their subject. As a library user, this means you can find lots of books related to one subject all in the same place! Take a look on either side of the book you're looking for, you might find something unexpected!
Read the number left to right starting with the letters. The first part of the number, HN 90 in this example, will tell you which bookcase to look at.
The second part S6 K45 will tell you which shelf to find the book on. The books should be arranged alphabetically/numerically by their call numbers.
The final part of the call number, e.g. 2022, tells you the year the book was published.
