Dewey isn’t perfect!?
Dewey Decimal “Problems”
1. Subjects can be found in multiple Dewey areas.
2. Dewey places fiction books in the 800s, divided by country and date.
3. Dewey places biographies in the area of the subject’s profession.
![Page 48: Libraries and Dewey Decimal Classification](https://reader034.vdocuments.net/reader034/viewer/2022052310/5558e3c4d8b42ab8168b4bca/html5/thumbnails/48.jpg)
Same subject . . . in three sections?
Gardening
580Botany
635Gardening

Problem: The same subject can be foundin multiple Dewey subject areas
Solution: use the library catalog orask a librarian
