The Free Decimal Correspondence

"The Free Decimal Correspondence, or FDC for short, is a set of decimal numbers ranging from 000 to 999[.9999...], each associated with a particular subject, discipline, or group of subjects and disciplines. It's intended to be reasonably compatible with existing and commonly used library decimal classifications and subject headings, but also as freely usable and adaptable as possible. ...

Many libraries use such a system to arrange their books on a shelf (or their electronic items in a list) in the order given by the decimal numbers, so that they're organized in a general hierarchy with items on similar subjects located near each other. These numbers, when assigned to particular items, are referred to as 'call numbers'. For instance, if you're interested in political science, you could go to the items with call numbers between 310 and 320, and find lots of political science resources on similar topics presented next to each other. And you'll find other social sciences nearby as well.

Decimal systems can also be used to give a language–independent representation of a particular concept. (So, for instance, 'mathematics' in English and 'matematica' in Italian can both be expressed by the FDC decimal code '510'.) You can also use FDC to label sets of items you've associated with particular decimal numbers and ranges. ...

The most commonly used decimal call number system is the Dewey Decimal Classification (DDC). We've tried to make this classification compatible with the present–day Dewey system, so the numbers will in many cases be similar in DDC and FDC for similar subjects."
