Want to take a quick browse through a list of all JC suggestions? Please take a look at our new Mendeley group. Mendeley is a referencing software tool that handles your PDFs in a neat order, without the need to remember or design your own ‘windows folder system’. Of course, other software also works (papers, reference manager), but they don’t have the opportunity to see use data from users around the world to use in the development of alt.metrics. Mendeley was chosen for this blog for it is targeted at working in teams: now only authors of the blog are administrators of this group and you can only watch, but with a mere mouse click we can invite to help build an impressive list of seminal papers on causal research.
