How do you pick new books to read?

Where I work, there is a daily poll of employees that asks all sorts of random questions. One came up recently that caught my eye – it was asking what made us buy a book. I voted, of course, and was able to see the total results shortly after. I watched the tallies during the day and took a snapshot at the end of the day (below).

If you exclude the last comment, the order seems to be:

1. Favorite author

2. Friend recommendation

3. On-Line reviews

4. Media buzz

5. Cover

So what about you? How do you find the next book you want to read?
