This will be old news for some of us, but just in case you haven’t heard (I was embarrassingly late seeing it myself), the ALCTS CaMMS Competencies and Education for a Career in Cataloging Interest Group has posted a draft document on cataloging competencies.

I am not sure how long the review period is—any reader who knows, please chime in with a comment here. It is worth visiting the draft even if you don’t think you will have anything to say, both for the content of the document itself and for the many comments already added.
