Companies are figuring out every way to maximize the Facebook experience while users are online, but what about when they’re not logged in? A new project called Yearly Leaf is conducting an experiment in social permanence: by connecting with Yearly Leaf, Facebook users can order a moleskin-bound book recapping a year of their life on the social network.

Seattle-based Yearly Leaf, started by Mark Michael and Daniel Rust, takes the special moments from a Facebook user’s year — birthdays, milestones, parties, etc. — and prints them in a book. Michael and Rust formed Yearly Leaf about two years ago, and printed a few books as a test. After the two guys spent some time tweaking it and perfecting it for a while, Yearly Leaf was ready for its official debut on Wednesday.

Here’s what one of the pages looks like:

Michael told AllFacebook that the idea started around the time Facebook Co-Founder and CEO Mark Zuckerberg announced in October 2010 that users own the data connected to their profiles. The duo started thinking of ways that they could take moments from Facebook pages and transcend them into something a little more permanent. They didn’t want to do simply a photo book, but something that encompasses all that someone went through in a year.

Michael explained to AllFacebook what he’s hoping Yearly Leaf can accomplish:

When you go through it a couple pages at a time or you go through it all at once, you’re just like, “Oh my God, I did all these things!” You’ll really see a story coming together, whether it’s that restaurant you checked into ten times or that restaurant you’ll never go back to or that concert or that wedding you attended or whatever you did.

The book — regardless of how many posts you made in 2011 — will cost $49. Or, for the more crafty, Yearly Leaf offers a Do-It-Yourself option, where they send users all of their data in 2011 for $1.99. This way, users can relive birthdays, weddings, parties, anniversaries and other events through scrapbooking or calendars or whatever other format they prefer. Users can pick 2010 or 2011 right now.

In the near future, Yearly Leaf plans to expand its offerings into groups, as some people set up groups to plan and coordinate outings such as camping trips. This way, users can have a tangible reminder of an event — and everything that went into it.
