In-house production has been reduced or outsourced, and in 2023 Elsevier began using AI during production without informing the board, resulting in many style and formatting errors, as well as reversing versions of papers that had already been accepted and formatted by the editors. “This was highly embarrassing for the journal and resolution took six months and was achieved only through the persistent efforts of the editors," the editors wrote. "AI processing continues to be used and regularly reformats submitted manuscripts to change meaning and formatting and require extensive author and editor oversight during proof stage.”
