Melvil Deweyborn Dec. 10, 1851, Adams Center, N.Y., U.S.died Dec. 26, 1931, Lake Placid, Fla.American librarian who devised the Dewey Decimal Classification for library cataloging and, probably more than any other individual, was responsible for the development of library science in the United States. Dewey graduated in 1874 from Amherst College and became acting librarian at that institution. In 1876 he published A Classification and Subject Index for Cataloguing and Arranging the Books and Pamphlets of a Library, in which he outlined what became known as the Dewey Decimal Classification. This system was gradually adopted by libraries throughout the English-speaking world. In 1877 Dewey moved to Boston, where, with R.R. Bowker and Frederick Leypoldt, he founded and edited the Library Journal. He was also one of the founders of the American LibraryAssociation. In 1883 he became librarian of Columbia College, New York City, and there set up the School of Library Economy, the first institution for training librarians in the United States. The school was moved to Albany, N.Y., as the State Library School under his direction. From 1889 to 1906 he was director of the New York State Library. He also served as secretary of the State University of New York (1889–1900) and as state director of libraries (1904–06). He completely reorganized the New York state library, making it one of the most efficient in the United States, and established the system of traveling libraries and picture collections.

James E. Walker Library Middle Tennessee State University Dewey Decimal Classification Let's Do Dewey • The Dewey decimal system is used in more than 200,000 libraries throughout the world and it has been translated into 35 languages. The Dewey decimal system coordinates materials on the same subject and on related subjects to make items easier to find on the shelves.. All knowledge is divided into ten main classes, which are listed below. More info about the DDC • 000 Generalities • 100 Philosophy and Psychology • 200 Religion • 300 Social Science • 400 Language • 500 Natural Science and Mathematics • 600 Technology (Applied Sciences) • 700 Arts • 800 Literature • 900 Geography and History

James E. Walker Library Middle Tennessee State University More about DDC Let's Do Dewey • Each of the above classes each have ten divisions. These divisions are further divided--and then further divided. Each division becomes more specific. The more numbers, the more specific the subject. In this way, the Dewey classification system progresses from the general to the specific. For a detailed summary for each number see the Dewey Decimal Classification System Summaries. The decimal place is used to make the number even more specific. • Let's see if we can catch a butterfly.

James E. Walker Library Middle Tennessee State University Classification for Butterflies 1 Let's Do Dewey • To find the classification number for butterflies, we need to start with the class for natural sciences the 500's This means that the first number of the call number will be a 5Let's look at the ten divisions of this 500 class. • 510 Mathematics • 520 Astronomy • 530 Physics • 540 Chemistry • 550 Earth Sciences • 560 Paleontology • 570 Life Sciences • 580 Botanical Sciences • 590 Zoological Sciences

James E. Walker Library Middle Tennessee State University Classification of butterflies 2 Let's Do Dewey • Butterflies will be classified under the Zoological Sciences 590 Now we know that the second number of the call number will be a 9 Let's see the divisions of the 590's to find the next number. The Zoological Sciences, the 590's, are divided into ten divisions also. • 591 Zoology • 592 Invertebrates • 593 Protozoa • 594 Mollusa • 595 Other Invertebrates (worms and insects) • 596 Vertebrates • 597 Fishes • 598 Reptiles and Birds • 599 Mammals

James E. Walker Library Middle Tennessee State University Classification of butterflies 3 Let's Do Dewey • Insects, including butterflies would be under 595.Now we have the first three numbers of the call number 595 The 595's are further divided by the use of decimals to specify what type of insects.---Beginning to get the picture...... • 500--Natural Science • 590--Zoological Sciences • 595--Other invertebrates • 595.7--Insects • 595.78--Lepidoptera • 595.789--Butterflies

James E. Walker Library Middle Tennessee State University Call numbers Let's Do Dewey • What is a call number? • In large libraries, it is possible that many books will be classified with the same Dewey classification number. The library must give each book a unique number that serves as the address for locating each book on the shelf. • To create this unique number, a Cutter number is added to the classification number. • The call number for a book in the library is composed of two parts—the Dewey Decimal Classification number and the Cutter number.

James E. Walker Library Middle Tennessee State University Cutter number 1 Let's Do Dewey • The cutter number for a book usually consists of the first letter of the author's last name and a series of numbers. This series of numbers comes from a table that is designed to help maintain an alphabetical arrangement of names. • Conley, Ellen Conley, Robert Cook, Robin Cook, Thomas C767 C768 C77 C773

James E. Walker Library Middle Tennessee State University Cutter number 2 Let's Do Dewey What if the library has several works by the same author? How do we keep the call number unique? To do that a work mark or work letter is used to distinguish the various works of a single author. The work mark is a lower case letter that is usually the first letter of the title of the book. Let’s look at the Harry Potter books. Chamber of Secrets 823.914 J.K. Rowling R797c Prisoner of Azkaban 823.914 J.K. Rowling R797p Goblet of Fire 823.914 J. K. Rowling R797g

James E. Walker Library Middle Tennessee State University Cutter number 3 Let's Do Dewey REMEMBER: the cutter number is a decimal not a whole number and is also read digit by digit. Look at these carefully 813.54 813.54 813.54 813.54 813.54 C767s C768m C77a C77g C773e

James E. Walker Library Middle Tennessee State University Literary Criticism Let's Do Dewey In order to keep books of literary criticism about an author and his/her works shelved together, a capital Z is placed at the end of the first cutter line. The capital Z, the last letter in the alphabet, insures that all criticisms are shelved after the author's work. A second cutter line will begin with the first letter of the name of the author of the criticism. Let's look at an example of where a work of criticism would be shelved.

James E. Walker Library Middle Tennessee State University Literary Criticism Let's Do Dewey The call number for Harry Potter and the prisoner of Azkaban by J. K. Rowling is… 823.914 R797p The call number for J.K. Rowling’s Harry Potter novels: a reader’s guide by Philip Nel is…. 823.914 R797Z N32

James E. Walker Library Middle Tennessee State University Literary Criticism Let's Do Dewey 8 Literature 2 English literatures 3 English fiction . 9 1900 1 20th century 4 after 1945 R Rowland 797 Cutter number Z Literary criticism N32 is for Philip Nel, the author

Biographies are histories of person’s lives. The call numbers for these books also have a second cutter number. Let’s look at he biographies of George W. Bush. The biographies of George Bush are classified as 973.931 B62 James E. Walker Library Middle Tennessee State University Biography Let's Do Dewey

To keep all the biographies about a person shelved together and to create a unique call number for each book, a second cutter number is assigned for the author of the biography. James E. Walker Library Middle Tennessee State University Biography Let's Do Dewey George W. Bush presidency: an early assessment edited by Fred Greenstein. 973.931 Administration of George Walker Bush B62 Cutter number for subject of biography(Bush) G85 Cutter number for author/editor, Fred Greenstein

When a call number has more than two cutter lines, this can be confusing for shelvers and library users. When shelving, it is important to remember that the second cutter line will come before the work marks on the first cutter line. Some students remember this by the saying Nothing before Something James E. Walker Library Middle Tennessee State University 2nd cutter numbers Let's Do Dewey

Help for the confused • A quick help is to think of Dewey numbers as money. For example $331.02 is less money than $331.20 and $895.1678 is less than $895.40. Following this scheme, look for library books shelved from least amount $000.0000 to the most $999.9999. • You may need just a short review of decimals. Practice comparing decimal numbers

Review of decimals • Let’s look at the number 636.8 The decimal point separates the whole number from the decimal number which is only a part (fraction) of a whole number. The first number to the right of the decimal point is for tenths. 636.8 is equal to 636 and 8 tenths or 636 and 8/10 636.85 The second number to the right of the decimal point is for hundredths. 636/85 is equal to 636 and 85 hundredths or 636 and 85/100 636.859 The third number to the right of the decimal point is for thousandths. 636.859 is equal to 636 and 859 thousandths or 636 and 859/1000

Another hint • 311.0942 • 311.0700 • 311.1160 • 311.2000 • 311.0180 • 311.1260 Another quick help is to add zeros to the end of the numbers. Now you can see that 311.0180 is the smallest number and would come first on library shelves followed by 311.0700 and then 311.0942. Notice that we look at the first digit, then the second etc.
