First, look up the book in the library catalog by using the Catalog tab on the library homepage.
Look at the location information on the item (if its status is "ONLINE," simply click the "Access online version" link):
Generally, available books will be located in "Michnr Stacks," the main stacks on the 2nd and 3rd floors of Michener Library. However, some are in separate locations such as "Michnr Ref" (reference), "Michnr Youth," or "Michnr Gov," for example. Check the Library Map to find these sections. Anything starting with "Music" can be found in Skinner Music Library.
Next look at the call number. Most books have a Library of Congress call number unless they are in a special section (e.g. gov docs or youth). Start with the first letter. Letters starting with A-F are on the second floor. Letters G-Z are on the third floor. Then look at the first set of numbers as a whole number and find which shelf range includes that number (ranges are listed on the end of each row).
Then narrow even further by the letter and numbers after the period. If you need more help ask a librarian or learn more at this website: The Library of Congress Classification System (LC)
