If you are on or near our Alva campus, you can browse or search the collection on-site at the J. W. Martin Library and check out books with your student I.D. card.
If you are at another location, you can order books to be sent to you through the mail.
Let’s take a look at the spines from some books in our collection:
Those labels contain what are called call numbers. The call number tells you where in the library a book is shelved. When you look up a book, you will typically receive the call number, and you can then go to the shelf where the book is located.
There are actually two sets of numbers here, and we’ll explain each in turn:
Now take a look at the end of one of our shelving units:
As you can see, each shelf has a range of numbers printed on it. So when you find the call number of the book you want, you can retrieve the book from the shelf with the appropriate range. If you want a book that has the call number 708.051, as shown above, you would go to the shelf containing books with call numbers 708.05 to 735.045.
Dewey Decimal Numbers
Melvil Dewey invented this system for organizing libraries in . The numbers represent categories and sub-categories of the fields of human knowledge.
Conveniently, you don’t need to know what the numbers mean to use the system—you just need to know that books are arranged in numerical order on the shelves.
Here are the major categories of Dewey Decimal Classification:
|000–099||General Reference & Information Science|
|100–199||Philosophy, Psychology, & Logic|
|400–499||Natural Science & Mathematics|
|600–699||Technology, Applied Science, & Medicine|
|900–999||History & Biography|
This system ensures that books about the same subject are grouped together. So if you find one book on the subject you’re researching, it’s a good practice to scan the other books nearby to see if they will be valuable to your research also.
The second number on the spine is the Cutter number.
You don’t need to know exactly how Cutter numbers work; the important thing to understand is that this number is a code that is a shortened way of writing an author's last name. So after a book has been assigned a Dewey decimal number representing its subject, it also gets a Cutter number for its author.
On the shelves, the books are arranged numerically by Dewey decimal number and also alphanumerically by Cutter number. These numbers together make up the call number. You should always be able to find a book on the shelf if you have the call number—but if you can't find it, you can ask for help from the library staff.
The first letter of the Cutter number is always the first letter of the author's last name. After that comes a combination of other numbers and letters. Probably the most confusing aspect of the Cutter Number is that the numerals are ordered like the numerals after a decimal point. That's why, in the photograph used as our example, C762c comes after C7393c.
