Locating Books

Books are arranged by call number, indicated by the blue arrow in the image below. Be sure to check the status of the book, too. If it says "available," the book is on the shelf. If the book is checked out, the status will say "checked out."

Books with call numbers A - N are on the first floor of the library.
Books with call number P - Z are on the second floor of the library.

Call numbers are in the Library of Congress system. Each letter corresponds to a certain subject. For a list of letters and their subjects, see http://www.loc.gov/catdir/cpso/lcco/.

Reference books, print periodicals, movies and music are on the lower level of the library.

What are Boolean Operators?

 

Boolean Operators are:

AND
OR
NOT

Use them to connect your search terms.

AND: gives you fewer results.  Use AND for different concepts to narrow your results.
Example: capital punishment AND Illinois
This search will find items about capital punishment, but only if the word "Illinois" is included.

OR: gives you more results.  Use OR for synonyms and related concepts to increase the number of results.
Example: capital punishment OR death penalty
This search will find items that have the term "capital punishment" or "death penalty."

NOT: Use NOT when you want to eliminate irrelevant terms from your results.
Example: java NOT coffee
If you're searching for Java script, this search will not give you irrelevant items about coffee.
