Library resources go through a review process.
   Materials are added that have been evaluated for quality and have
   undergone some type of editorial review. 

Library resources are available for your use at a lower cost.
   Libraries are able to purchase one copy of a book or a database
   subscription which can be shared by many people.  Expensive scholarly
   materials as well as less expensive popular materials are available.

Library resources are available based on informational, not commercial, value.
   Libraries don't buy materials to re-sell them to patrons, so many materials
   can be found in libraries which no longer appear in bookstores or online.
   Libraries collect materials on unpopular topics as well as popular topics.

Library resources are organized.
   Items are organized so you can find all the resources on a topic. For example,
   books on a particular topic will be grouped close together by their call
   number in a library. Online library databases contain subject headings
   which can be used to retrieve all articles about a particular topic.

Library resources are meant to be kept permanently.
   A primary function of a library is to be an organized storehouse of
   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. They'll help you learn to
   use online resources and answer any questions that you have.
