Useful Slideshare Presentation on the Dewey Decimal System

So I found an interesting Slide Share presentation which I believe would be useful for our Library Attendants who require refresher training on the Dewey Decimal System. The slide share presentation provides useful information on:

1. DDC & OCLC Ownership.
2. DDC - History & Extent of Use.
3. Classification: What It Is and What It Does.
4. Development of the Dewey Decimal Classification.
5. Framework and Structure.
6. Summaries.
7. Exercises.

Take a look!
