Abstract
The field of computer science has been growing rapidly in the last 20 years. However, the Library of Congress (LC) classification only gives computer science a very limited space QA75-QA76, which is buried in the QA subclass for mathematics. Although LC call numbers for computer science may become very long, it is still impossible to differentiate a C programming book from a C++ programming book, or a data structure book using C language from an algorithm book in C language. This paper analyzes the historical reason for the current LC classification system for computer science. Compiling a sample data from Blackwell's North America's Approval Program Coverage and Cost Study, the paper calculates current and all possible subdivisions within Q class, and states that computer science has more books published in the last six years than in any other physical sciences, yet it takes only 2 out of 11,000 current subdivisions in LC class Q. The paper concludes by making a suggestion to create a completely new subclass QF for computer science.
