[T.B. Yoits]

The Dewey Decimal System was doomed with the advent of computers. Numeral systems are more limited and have more complications that Alphanumeric Systems, starting with the simple character count.

In a numeric system 0-9 give you a choice of 10 characters. (With restrictions on leading zeros which cause problems. For example: "5" and "005" are not recognized as the same unless the software is written to).

In an alphanumeric system, A-Z and 0-9 give you a choice of 36 characters.

Computer programs can query and sort with alphanumeric systems in ways a simple numeric system can't.

Ask anybody under 30 today what is a card catalog, and you will get blank stares.

Maybe the Babylonians had it right with their base-60 number system.
