At Millikin’s Library, we use a system called “Library of Congress” to organize our resources.
When you search in Millikin’s Online Catalog, to find if a book that is available for you to take home, look at the “Status,” the “Call Number,”and the "Location."
Here’s an example of a Call Number for Three Plays by Terrence McNally. In the online catalog, the call number is listed as PS3563.A323 A6 1990, with a location of "book stacks."
How the call number will look on the book's label:
PS (Find these letters using alphabetical order. PS comes after PR, but before PT)
3563 (Treat this 3563 just like any number. It comes after 3562, & before 3564. Call numbers may include decimals)
.A323 (After finding the PS section and the number 3563 area, use the alphabet again to find the As on the third line and fourth
A6 lines of the call number. Treat the numbers paired with the letters as decimals... 0.323 and 0.6 in this case)
1990 (The date the book was published, in this case, 1990)
