I'm blogging over on Samhain Publishing's blog today -- I'm talking about keeping track of the books I've read or bought. And my unfortunate propensity for buying duplicate books.
Since I posted it, Gizmo Guy has been scouring the web to see if there is indeed an app. Turns out there are several. I foresee a blog post here in the future rating them.
How do you keep track of what books you've read/haven't read -- I'm looking for a portable system you can take to the brick-and-mortar book store as well as when you're buying online.
