A call number is a unique number assigned to an item in the library. Call numbers tell you where to find items on the shelf.
Our library, like most university libraries, uses the Library of Congress (LC) Call Number Classification Scheme to organize books by subject.
It's complicated, because it's very precise. Follow the link below to the LC website to see how the system is organized. It only takes a minute to have a look.
The call number for the bookThe Philosophers of Greece is: B 171 .B78.
B: the section for General Philosophy - read it alphabetically. To get this book, find the "B" section in the library.
171: represents the "Ancient" time period of Philosophy - read it as a whole number. Find 171 within the B section.
.B78: specifies this particular book (the author's last name begins with "B") - read the letter alphabetically and the number as a decimal. (.78 comes before .9)
1986: sometimes the date of publication is included at the end, but not always. It's only important if there are several editions.
Within our Library there's a Government Publication area. These documents use a different classification system.
CA1: Canadian federal government documents
CA2: Canadian provincial government documents
