Thanks Olivia.... Unfortunately I don't have (or maybe it's I don't know!) by Athens username and password. i think my uni uses Shiboleth but that doesn't always work for me either! Will play around with google scholer though at some point.

don't be afraid to try the advanced search in Google Scholar - it's not really that advanced! Using boolean searching you should be able to combine, omit and link keywords together. Also you can search by author etc.

From my experience if you are on-campus and using Google scholar, if your library subscribes to a database it should bring you directly to the pdf. If it asks you to pay it generally means your library doesn't subscribe.
