I used a google doc this year which made it a lot easier but I have been doing it for some time and putting it up on lj (http://www.livejournal.com/tools/memories.bml?user=professoryaffle&keyword=books&filter=all)

I gave up on reviews in the last couple of years though

edit:You should also really read the Knife of never letting go, I suspect you would really like it, I bought a copy for nannyo I am sure she would lend it to you
