In an earlier post I mentioned the Royal Literary Fund's invaluable resources for students and other academic writers: their super Writing Essays guide, and their Dissertation Guide.
They've recently started two blogs. One is called Top Tips and is full of helpful ad hoc advice from the RLF Fellows to help you write more effectively. The second blog is called What's Happening and features reflections from Fellows on the link between their workshops with students, and their own creative writing.
Thanks to Dilly Fung (@DevonDilly) for bringing this to my attention!
