Index Notes


The Index and The Books

The Index is sorted by Dewey Decimal Classification, then by Artist if appropriate, then by author surname. Other sorting orders are possible. On the shelves the books are filed by Dewey Class but then randomly within each class. (Any volunteers to get them into the Index order?). 'Oversize' books are noted and are stored in the far-right cabinet irrespective of class number. Books with duplicate copies are noted.


Dewey Decimal System

You see the numbers on the spine of nearly every non-fiction library book. The Dewey Decimal System categorises all knowledge by number and is the most widely used book classification system. It provides an index to all classes of knowledge and so enables structured searches for information. The system is managed by the U.S. Library of Congress and is only available in full on payment of a fee.


This OyP Book Index has been compiled by several volunteers using a summary (and free) list of the Dewey Decimal Classifications. Generally only the first three levels of classification have been available, which is to say the first thousand numbers, 0-999. These classify the knowledge to major class groups below which are several sub classes. In assigning a number only the main topic of the book should be taken into account, and the narrowest and most exact class assigned. Some books could only be classified at the highest and most general levels either because we do not have access to the full Dewey system or for simple expediency.


To assist your search the Classes used in this index are listed below.
