You already had a session from Alastair in week 2 (on Google etc. searching) and you will have a further session from him this week (Groups 1 and 2) or next week (Groups 3 and 4)
What you need to do
Once you have had the 2nd session from the Alastair (i.e. this week for groups 1 and 2, next week for groups 3 and 4), make an individual post on your team blog, listing one new thing you learnt about Google or database searching.
A few of you have had a lot of experience in libraries before joining the course: so if you were already a search engine/ database wizard when you came to Sheffield, just say what your best searching tip is!
