The DDC Facts

 The DDC 

 Do you know

 Melvil Dewey was mathematician by education and never had any formal library education. 

It was his habit of parsimony which led him to invent a durable classification system for his library where he worked as a student. 

To him goes the credit of establishing the first library school in the world. 

NOTE:

The DDC is the mother of all modern library classification systems.

 All later systems have borrowed its major methods, namely division by discipline, depiction of hierarchy, use of decimal notation, and the relative index. 

It is the longest surviving classification system; it has the largest number of editions, 23 so far. 

It is the most popular general classification system used in 150 countries in all the six continents. Its use is still expanding. 

It was the first general classification edited online. 

It was the first to be commercially made available in electronic form. 

Its use is expanding despite being truly criticised for its bias towards western culture, defective structure, and lengthy notation. 

Its governing body is one of the best in the world.
