Dewey Decimal System
Once you have identified a book in the card catalog, the search begins! 
Remember, you will need to write down the important information from the card catalog, which includes the book's:
  • title
  • author
  • publisher and copyright
  • call number


The Dewey Decimal System is an organizational tool that uses numbers and letters to identify and shelf books. The call numbers are located in the upper left hand corner of the subject, title, and author cards. These match the call numbers on the spine of the books.

Books are categorized in several different ways. In the library, you will find groups of fiction, nonfiction, biographical, and picture books, each in a separate area. Each group is also shelved in a unique way.

Follow the directions below to learn how to find a book in each of these areas of your library.
 
Nonfiction
Fiction
Biographical
Picture

 
Nonfiction

Nonfiction books are those that provide factual information.

Nonfiction books are organized using the Dewey Decimal System. Their call numbers begin with a set of numbers and are sometimes followed by a set of letters.

The set of books below is shelved according to 
the Dewey Decimal System.

1. Go to the card catalog in your library.
2. Find a book that has numbers in the call number portion of the card.
3. Write down the call numbers, title, and author of the book.

Fiction

Fiction books are those that tell nonfactual stories such as novels and chapter books.

Fiction books are organized using only letters. They are arranged alphabetically according to the author's last name. If an author has written several books, then the books are organized secondarily by the title.

Finding Resources in the Library
 


Resources Available

In addition to topic-specific books, the library contains several other types of resources to assist in your research.  Each type of resource offers a unique approach to the presentation of information.
 
Magazines
Encyclopedias
Reference Materials

 
Magazines

Magazines can be a tremendous source of information. News, opinion-based articles, current events, advertisements, and factual information pieces are published in magazines. They often include vibrant photographs, as well, which add a new dimension to the research process.

The set of magazine titles below shows just some that you might be able to find in your library. There are hundreds, even thousands, of other magazines that you might find interesting and useful.
 


With so many magazines to look through, the task could potentially be overwhelming. Some magazines, though, publish an index that can be used like the card catalog for books.

(See diagram for information location.)

1. Go to the library and ask your librarian to help you locate the
        National Geographic Magazine Index.
2. Look up the subject "Egypt".
(Note: Subjects are listed in alphabetical order.)
3. You will find that Egypt is subdivided into two categories,
        "Egypt" and "Egypt, Ancient".
4. Count the number of entries under each heading.
5. Write down the title, the author, the month, the year, and the page numbers
       of an article you would like to read.
6. Find the magazine that contains the selected article.

Note:The identification structure for magazines is slightly different from other resources. Books are identified with an ISBN code, which can be found on the book and in the card catalog. Magazines, on the other hand, are identified using volume and issue numbers as well as the date of circulation.  These aspects of a magazine are important when seeking out the location of bound magazines and when documenting your resources.
 
Encyclopedias

Encyclopedias offer a wealth of information at your fingertips. These collections of books, each known as a volume, cover a wide array of topics.  Topics are often cross-referenced to encourage further investigation.
 

Encyclopedias, as with many other reference materials and organizational systems, organize subject matter alphabetically, both in the volume and in the index. Information can be easily accessed by using the encyclopedia's index.
Some encyclopedias include an index with each volume, while others have a self-contained index as one of the volumes.

1. Go to the library and find an encyclopedia index.
        (The World Book Encyclopedia is one of many great encyclopedic resources).
2. Find the entry related to "England".
3. Count the number of other entries related to this topic -
        some will be slightly varied, such as "English . . . ".
        These related topics tend to be more specific in their subject matter.
4. Find the primary location of information about England and
        locate the appropriate volume and page number.
5. Note that under the entry for England,
        there is a list of subtopics about which information can be found.
 

It is important to note that some subjects are categorized under alternative headings and may not be in the volume that initally comes to mind. Cross-referencing may take place at the end of the actual encyclopedic article or in the "See also" portion of the index entry.  For example, at the end of the entry cited above, "England" is cross-referenced as follows "English . . . and Great Britain in this index, and the list of Related Articles in the England article".
 
Reference Materials

In addition to encyclopedias, there is a multitude of other reference materials found in the library. These fact-filled books offer accurate and fairly current information, each with a slightly different purpose.

Below is a list of reference titles you may find in your library.
 

  • The World Almanac for Kids
  • The Kingfisher History Encyclopedia
  • National Audubon Society First Field Guide (various topics)
  • Animal Fact-File
