RefME is a free reference manager. It can help you capture references on the web and put them together into file format you can export and use in your thesis submission or project submission. For some general info on how it works and what it’s compatible with see this earlier post on LectureHub here. The video below will show you how to capture references on ncbi.nlm.nih.gov/pubmed, biopharminternational.com and books.google.ie to start with but it can do so much more. Well worth considering using it to help you with your thesis/essay writing.
