LibAnswers: Customer Services

The Library uses the Dewey Decimal Classification scheme (Dewey for short) to arrange books and other resources on the shelves so you can locate them easily. Here is how to use Dewey to find a book at any Library site:

Start by looking for your item on Library Search then, midway down the page, you'll see something like this:

Note how it reads: "Location: Main Library Blue Area Floor 2 370.193 B174".

This tells you the location you can find the book in the Library- Blue Area Floor 2.

Then the Dewey number, 370.193 B174. This tells you where to find it when you get to the Location.

What do these numbers next to the book's location mean?

The Dewey numbers are a "shelfmark" (on Library Search, this is the number next to the book's location). You’ll find one of these on every book in the Library - if you break down the information into three sections, it's easier to understand.‌‌

1. The numbers in front of the decimal point indicate the subject area (in this case 370). Look for this number first.
2. Next, look for the number after the decimal point (in this case 193). You should do this digit-by-digit, not as a whole number.
   In this example, look first for .1 then for .19 and then .193.
3. Now look for the letter(s) and number(s). Letters are shelved alphabetically, numbers are shelved in order. Letters are usually the initial letter(s) of the author's name (in this case, Burbules).

Shelves

• At the end of each shelf, there are signs that show the range of shelfmarks in that row.
• Rows run from left-to-right, and books are shelved from left-to-right.

Collections

• Sometimes, you will see extra letters before the shelfmark. This shows that a book is part of a collection within the Library. For example: N.E. 279.32/R29 is part of the Near Eastern collection.
• Find the collection first, before looking for the number.
