London-based Mendeley , which calls itself "the Last.fm of research", has announced that it's reached something of a milestone today - claiming 100,000 users and 8 million research papers uploaded to the site in less than a year since its launch. Furthermore, the online database is doubling in size every 10 weeks, says the company. That's pretty impressive stuff and should Mendeley's database continue to grow at the current rate they'll overtake Thomson Reuters' Web of Science, the world’s largest online research paper database, in April 2010.
