If you're a student of mine looking to contact me, you can (a) email me at a.m.gregory@reading.ac.uk, (b) catch me before/after class, or (c) call into G65 in the HUMSS building. My office hours are officially Wednesdays, 11am-1pm, but you should feel free to see if I'm in at any time.
Otherwise, see the links on the left for essay writing advice, as well as a collection of helpful links.
