It seems that ARe has heard some of the reactions to the front-paging of erotica that is not romance. Their response is to put it in a separate category. Um, okay. It's still not romance though. But I guess AERe isn't such a nice acronym. It also brings to mind the phrase "aere perennius" which, in the context of the medical treatment of erotic misadventure, is not generally good news.
"In order to improve discoverability for all, we’ve decided to create separate Erotic Romance and Erotica categories. The “old” Erotica category will soon be retired. All titles in that category will need to be re-shelved prior to its retirement to avoid inactivation."
