Evernote, the online productivity application that uses pictures, notes and other memory aids to ease information overload, has raised $4.5 million more for development and marketing of its product.

Although it began as a computer application, Evernote has been steadily expanding its support for other devices. However, its core functionality is the ability to organize life’s many tidbits of information.

For example, a user who took a picture of a restaurant receipt with his cell-phone could search for the name of the restaurant or the day of the transaction to find it again, via the program’s image recognition abilities. We’ve written more previously about Evernote’s uses.

This round appears to have shrunk considerably below what the company was seeking, likely due in part to the recession; chief executive Phil Libin told us in mid-2008 that Evernote was on the hunt for up to $12 million; according to TechCrunch, it may yet search for more. Russian firm Troika Capital Partners led the funding. The Sunnyvale, Calif. company previously took $6 million from angel investors.
