TITLE: Ideal Home Library Organizer features?
POST: Hi Bookit,

I'm a student in computer science who happens to both love reading and love keeping/looking at data of books I read (page counts per month or year, genre shifts with my age/the time of year I read the book, my ratings of books, etc.).  I've been keeping an Excel spreadsheet with this data for a little while now, but I recently discovered some of the home library organizers on the web and have tried using them, but none of them have really catered to my needs or wants quite how I'd like (mostly in terms of their organizational deficiencies), so I figured, since I am, after all, studying computer science, I could write one myself.  I'm worried, though, that I'll put something together that sucks because I fell victim to one of the pitfalls that other Home Library Organizers have.  Since I'm sure many of you have more experience with these things than I do, I was wondering if you had any tips about things that are essential, or things that should be avoided.  And plus, I'm sure you guys have a lot of awesome, creative ideas that are not too hard to implement but of which I wouldn't have thought, and which would make my program that much better.
TL;DR: 
I'm writing my own Home Library Organizer program.  What features do you think I should give it? What features do you think I should avoid?
