Classification Schemes

The classification scheme of the CDD library from 9/7/2017-01/30/2023. 

Last updated 2/27/25

This document contains the original ASD classification used in the CDD library, a draft classification I made for a meeting with stakeholders to discuss updating the classification, and then finally the classification scheme depicted on the poster. The discussion was very helpful to identify ways not only the classification, but the collection itself was not being responsive to the needs of staff and patrons. 

Over the course of my time at the CDD I kept a document filled with thoughts, drafts, questions and considerations regarding the classification scheme. Any time a problem presented itself or I thought of a potential solution or way of reclassifying things I tried to write it down. The are also several areas I intended to make changes to in the future (like creating an "Education" and "Medical" classification) as well as significant updates to existing classifications. 

A fantastic resource to explore how items are classified according to different feedback and to see how other libraries classify or catalog an item. Even if you are making your own system of classification from scratch, you're not starting from nothing! I used this tool frequently when I was unsure how to classify an item to see what elements other librarians and library workers identified as the most important and then compared it against the CDD scheme.
