Dewey Decimal System
Dewey Decimal System (DDS)
Just like the grocery store separates the food into different sections such as: dairy products, meat, and produce is exactly how the DDS works.
Melvil Dewey created the Dewey Decimal System (DDS) in the 1800’s so that all the books would be organized by their subject.
Dewey Decimal System (DDS)
To find a book, you must locate the item’s call number.
The call number is the address of where the book lives on the library shelf.
You can find the item’s call number on the spine of the book, that is the part facing out on the library shelf
Dewey Decimal System (DDS)
1. Numbers
2. Letters
3. Year
There are 3 parts to the call number:
The numbers are the Dewey subject area of the book.For example, if the item has number 200, it has to do with religion.
The letters are usually the first three letters of the author’s last name.
The year is the year the book was published.

To find items using the DDS, search the call numbers in this order:

2010
These call numbers are in order:

182.6000
STA
2007
182.6000
SVE
2005
182.61000
ALT

Using the previous example:
If a call number contains only one decimal place, imagine that it has an endless amount of zeros after that decimal to find its numerical place.

182.6000 is the same, so STA comes before SVE
182.6000 comes before 182.6054
182.6054 comes before 182.6100
Remember that these are the call numbers:
