Libraries Begin

It was during the 1800’s that libraries were beginning to spring up around the country. The printing press had made more and more books available to the general public, and more and more people were learning to read.

Page 3: Understand Dewey

A Problem Evolves

Melvil Dewey was a very bright but frustrated librarian. As more and more books were added to his library collection, he found it difficult to locate materials.

Being a resourceful young man, he decided to create a standardized numbering system for classifying nonfiction books in a library.

Page 4: Understand Dewey

How Should Dewey Start?

Dewey wanted a system that put subjects into ten basic areas. (That’s because our numbering system is based on “ten”.) He wanted each book to have a specific number on the book spine so that the book would have a specific location on a library shelf.

If he used decimals with his base ten numbering system, he figured he could create detailed numbers for detailed subjects.

And……….

These are the basic ten sections of every library that uses the Dewey Decimal System. And, most libraries for schools and the public use this system.

Subjects ?

Dewey chose his ten basic subject areas by pretending to be a caveman. What kind of questions would the “first man” ask?

Dewey also wanted to be able to include subjects that were yet to be created due to future technology. (Smart guy, huh?)

Generalities

UFO’s) They are not really fiction or nonfiction.

Page 29: Understand Dewey

What about Subdivisions?

Each of these ten general subject areas can be subdivided indefinitely. The more specific the number, the more specific the subject.

For example:

How Are Dewey Numbers Assigned?

Every library uses the Dewey Decimal Classification Book.

This book has all of the number divisions and subdivision listed.

The librarian uses this book to select the correct Dewey Decimal Number for each title in the library.

Page 32: Understand Dewey

Find that Book!

Look up a title in the library computer. Write down the Dewey Decimal Number. Go to the nonfiction section of the library. Follow along the shelves numerically until

you locate the book. All books on the same subject will be

placed together on the shelf. Thank You, Melvil Dewey!
