Waldo Library uses Library of Congress Classification (LCC) for the majority of our collection and Dewey Decimal Classification (DDC) for children's books. DDC call numbers can be read as a regular number with a decimal while LCC is a bit more complex with letters and numbers. The videos below explains how to find books using an LCC call number. If you need help, go to the Service Desk at the front entrance.
Encyclopedias and dictionaries are a great place to get a quick definition or brief overview of a topic.
