Basically it works on the principal of books being catalogued in ascending numerical order. When two or more books have the same classification number, the system sub-divides them alphabetically. We use a call number, which is usually the first letter, or letters, of the author's last name. Or we use the title if there is no identifiable author. And that's the basics of how it works!
