Library resources go through a review process.
They've been checked by an editor or peer-reviewed, then selected by librarians--whether books, magazines, journals, or online databases. The library collects sources considered reliable, historically relevant, and valuable.

Library resources are free or discounted for your use.
Libraries purchase one copy which can be shared by many people.

Library resources are organized.
Items are organized so you can find all the sources on a topic. For example, when you search for a book in the library catalog you will get a call number. The books shelved nearby will cover a similar topic.

Library resources are meant to be kept permanently.
A primary function of a library is to store information published throughout time. As well as finding very current information, you can also find books that are no longer published and older issues of magazines.

Library resources come with personal assistance.
Libraries have staff who are trained to help you find what you need.
