The number of people boycotting Elsevier keeps going up!  Here's the graph for 2013.  See the sudden increase at the end?  That's because Elsevier forced the paper-sharing website Academia.edu to take down some papers. 

In retaliation, Academia.edu sent out emails like this:

Unfortunately, we had to remove your paper [...] due to a take-down notice from Elsevier.

Academia.edu is committed to enabling the transition to a world where there is open access to academic literature. Elsevier takes a different view, and is currently upping the ante in its opposition to academics sharing their own papers online.

Over the last year, more than 13,000 professors have signed a petition voicing displeasure at Elsevier’s business practices at www.thecostofknowledge.com. If you have any comments or thoughts, we would be glad to hear them.

Join in!  If you haven't signed the petition yet, now is a good time!

And here's a question: what made so many people sign the petition in May?  The bottom of this graph is not zero, it's 12,500 people, so the rise is not as impressive at it looks - but still, something happened in May.
