Computer Science - Subject Classification System      שיטת המיון במדעי המחשב

The library's classification system is unique to the library and aimed at the specific needs of its users.
The system is maintained and updated by staff members.

Our computer science classification numbers run between the numbers 210-282.
Each number represents a subject.
For example: The books on artificial intelligence are classified as 236.
