Types of Numerical Filing

There are three types of numerical filing. They are

1. Consecutive Classification: Folders or files are arranged in a strict order from 1 onward. Each folder is numbered according to either subject or name and placed at the near to the existing folders.

2. Dewey Decimal System: This type of classification is used in libraries. Each digit stands for one classification. For example 123.456 stands for sociology (1), commerce (2), Accounts (3), Decimal relates to Management Accounting (4), Accounts for Decision Making (5), Capital Budgeting (6).

3. Terminal Digit System: This type of classification is carried on to expedite reference and to facilitate the transfer of old records. Under this system, the first terminal digit is taken to be the digit in unit place, the second terminal digit in the tens place and so on. Thus, all the files with the same last two digits are filed together; then the files with the preceding two digits and so on. For example

Under — 01:01, 101, 201, 301, etc.
Under — 02:02, 102, 202, 302, etc.
Under — 03:03, 103, 203, 303, etc.
