A short introduction to the Library classification system, in video and text.

Once you've found the location of the shelves where your book is stored, you'll have to find the right shelf, and the book amid all the other books on the shelf.

A book's call number serves as an address for its location in the library. Understanding how the system works is like understanding North, South, East, and West.

LCC is an alpha-numeric system, but it can get a little tricky, so let's take it line by line.

A call number generally has four or five lines (when displayed on the side of a book).

The first line consists of letters, which go in alphabetical order:

E

The second line consists of numbers, and should be treated as whole numbers (18 comes before 125, etc.)

The third line consists of a single letter and numbers.

Look at alphabetical order first, and then read the numbers as decimals (not whole numbers). So, for example, on the third line ".G53" would come before ".G6" because the decimal number 0.53 is smaller than 0.6.
