I have been using Mendeley since Arianna and Anthony blogged about it. It is the best reference management system I have ever used (and I strongly recommend everyone at the lab to use it), with its “intelligent” reference incorporation, identification and annotation functions. On one hand, I love using it, and on the other, I would like to use it on all my computers/laptops (one at the lab and two at home). But the “headache” for me is to separately and frequently transfer and update all the electronic files within the three devices.

Here comes Dropbox!

Dropbox has helped me to solve this problem. It is, rather than an online storage space, an online agency which via internet helps to link files (up to 2 GB for free) across computers. So all the files are stored within one computer, then via Dropbox, you can view/drag/add files through a "Dropbox" folder placed at any computer. Combined with Mendeley, it brings great convenience to manage, read, and make notes on references.

Another feature of Dropbox is that it can temporarily convert a PDF file to an online link, which avoids the difficulty of emailing out big files.

For more details, here is a video tour.
