Organizing your PDF life: Papers

How do you organize all the PDF files on your computer? For years I've been frustrated with my manual labeling system on my Mac laptop. I have scientific articles all over the place on my desktop and can't find any of them when I want to. It's like looking for that one missing sock that eloped. Frustrating.

Then one day my Chair, Dr. Mike Callaham, told me about this great software called Papers (link). I don't have any affiliation with the software. It is the best $42 I've spent in a long time. Considering that I hate purchasing software (I want everything to be free and open-source), that's saying something.

The kicker is that this works only on a Mac. The software matches your PDF with Pubmed citations, allows you to make notations, is linked with Google Scholar, catalogs your PDFs, and has a search feature. For an extra $15, you can also get the iPhone version which syncs with your desktop version. An amazing platform.

In theory, I can read EM Clinics of North America review articles while sitting on the beach or sitting in boring meetings. OK, I said "in theory".

Question for you: What favorite software do you have on your computer?
