Recently, I was discussing media use patterns with Erin Reilly, the research director on Project NML. One of the things we started talking about was what a modern library user does.
I'm sure that many people use libraries in many different ways, but for me, a library mostly functions as an aesthetic space. I like to go to beautiful and monumental libraries because they inspire me and make me think about how noble the pursuit of knowledge is.

I like to go to small, stuffy, hot libraries and work in a carrel because I associate carrels with being a serious student: I never feel like I am
really writing a term paper unless I'm writing it in a carrel.

I like to walk through the stacks of a public library because I am more likely to pick up a book I've never read before if I get the chance to pick it up, look at the cover, and turn it over in my hands.

So the idea of a physical library is pretty important to me, but not for the reasons that one might expect. I spend a lot of time in libraries, but unless I'm just trying to kill time, I don't actually go to the stacks and look for books to check out very often. Instead, I use online catalogs as if they were Netflix. If I want to read a specific book or books on a specific topic, I go online and search for them in the catalogs of all the libraries near me. Then, I order them and just go pick them up when they're ready. I use the "search" function in very specific ways, to find the particular information I need.
But what about the Learning Library? I envision the Learning Library as a tool that includes both aspects of a library: a tool where you can either browse around and have fun or where you can look for a very specific skill that you want to learn about and zero right in on it. I also hope that the Learning Library will be an inspiring virtual place. That might be a lofty goal, but I think it's an achievable one. One of the goals of the Learning Library is to emphasize how much everyone can create and achieve in our participatory culture. I think that's a pretty inspiring idea.
So I'm going to try and keep the idea of a physical library in my head as I work on the not-so-physical Learning Library. I wonder what my children will think of when they think of the word "library" - will they enjoy looking around in the stacks? Will they even know what a carrel is? Or will they associate the word "library" with projects like the Learning Library? I suppose that only time will tell.
