This week’s tip is a bit off-topic (as in genomics databases), but it is science/biology-related and something we all need. There are a lot of reference management software possibilities out there like EndNote, some great web 2.0 social networking sites like Connotea (Nature Publishing) and CiteULike (Springer) and some PDF management tools. Mendeley wants to be all three. I like the idea a lot. Instead of having 2 or 3 separate applications, desktop and/or web, etc., you have one to rule them all. Of course EndNote has EndNote web, but it’s not free (Mendeley is free, and the features they offer now will stay free. They will offer new features for professional users later with a fee). You can export your references in Connotea and CiteULIke, but it’s an extra annoying step. My first experiences with Mendeley have been quite positive, so I thought I’d introduce them to you here.
