Commutative rings / Ayman Badawi, editor. (OCLC #50857508)

A sharp-eyed patron browsing books in QC (Physics) spotted this book next to Fourier’s “The analytical theory of heat”, and wondered if it was out of place: “Should it be in QA instead?”

The book was labeled QC 251.3, so he went to QA 251.3 and indeed, found lots more books on commutative rings and algebras. Somehow our catalog ended up with a bad typo!

We re-classed the book under QA 251.3 (the number in the OCLC master record) and re-labeled, so it can now be with its friends on the shelf and more likely discovered by interested browsing patrons.
