The Library of Congress Classification System (LCC) organizes materials into 21 branches of knowledge. These basic categories (labeled A - Z, with the exceptions of I, O, W, X and Y) are then divided into more specific subclasses by incorporating additional letters.
The Library of Congress Classification (LCC) System doesn't use the following letters: I, O, W, X, and Y. There are different reasons as to why these letters aren't used; for example, the letter I looks a lot like the number 1, and the letter O is almost indistinguishable from the number 0. The LCC consists of 21 main classes, and as a result there are some letters leftover. In the future, additional classes may be added, and the last three letters (W,X, and Y) might finally be utilized.
