About a year ago I wrote a long post that discussed both my general approach to working with academic PDFs as well as the specific Apple (OS X/iOS) software I use to manage my own workflow: Sente. I still consider Sente to be a kind of gold standard for reference management software, but there are a couple of things about it that lead me to regularly check out the competition. One is that it only works on Apple products and many of my students are Windows users. The other is that, even on the Mac, it does not work within the web browser itself, but forces you to launch the app and use its own built-in web browser, which always interrupts my workflow. In my last post I mentioned a few other issues and briefly surveyed the competition; however my current work environment has me on a Windows 7 computer and so I decided to look again at the competition, especially cross-platform solutions. The first one I discovered is ReadCube but I found it just didn’t meet my needs. It didn’t do a very good job getting citation information (I had lots of errors in my metadata) and the iPad app was too limited for my needs. However, another service turned out to be more promising: Paperpile, and I thought I’d write a short post about how I’m using that.
