In this paper, I want to celebrate the progress of OA journals and the launch of the OASPA (Open Access Scholarly Publishing Association) by setting out what I see as the 10 greatest challenges facing OA journals. I want to do this without pretending to set the association agenda and without presupposing that association members don’t already know these challenges very well. I m not a member of the association or even a publisher. I merely want to see OA journals succeed. In what follows, when I say "you", I m talking to those who edit or publish OA journals. I start with three disparities: the gap between journal performance and what prevailing metrics say about journal performance (#1); the gap between the vision of OA embodied in the Budapest, Bethesda, and Berlin statements and the access policies at 85% of OA journals (#2); and the gap between a journals quality and its prestige, even when the quality is high (#3). Then I move on to seven kinds of doubt: doubts about quality (#4), preservation (#5), honesty (#6), publication fees (#7), sustainability (#8), redirection (#9), and strategy (#10).
