Springer Reading Rooms
Until the end of February, Springer has granted open access to some journals. I got an announcement for the Philosophy Reading
Group Room, including Erkenntnis (alongside Husserl Studies, Journal of Bussiness Ethics and Criminal Law and Philosophy). The Reading Room looks like a neat project, with the journals being changed every couple of months.
Looking around the Springer Hive should yield interesting results at this time of year. The new journal Evolution: Education and Outreach is free as well (for the time being at least).
