1099-MISC: Schedule C or E?

My husband used to work as a freelance editor of technical books. He received royalties from the sales of those books. I always filed a Schedule C-EZ for this income. He now is a full time employee in a different industry (online media), but still receives royalties from those sales which is reported on a 1099-MISC as box 2 (royalties). Do I still file this on the schedule C (and pay self-employment taxes) or does it now go on Schedule E?  Just to note again, he was not the author of these books.
