At some point in time I used to know a large amount of the books I have, but now I have piles of them sitting on different parts of the room and some of them getting dangerously high. When I go through a few piles, I realize there were some books I wanted to read and follow up on at a later stage. I know the books that I read but the ones that go unread sometimes disappear and I forget to follow up on them, until I find them later hidden inside a cabinet or the back of a shelf. So to organize this large mess of items there are two softwares that I have been looking at, one is the usually awesome Delicious Library which has advanced greatly but there is one other very viable option which is Collectorz Home Library, two options to choose from.
