Library resources go through a review process.
Librarians select books, magazines, journals, databases, and Internet sites. The library collects sources considered reliable, historically relevant, and valuable.

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 near the same call number will cover a similar topic.

Library resources provide access to current and historical information.   
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.  The staff will assist you in the use of print and electronic resources and answer any questions that you have.
