This is so great for my needs! Specifically, I didn't get this for books but for art, I wanted to get a little light  like this so I could draw more easily in areas with dim lighting, I don't always like drawing in my desk area and this is perfect! The neck is so very flexible, moves very easily, the clamp expands pretty wide, it is very bright and the two brightness settings are great. I highly recommend it but this will probably be too bright for some depending on the reasons for wanting to use it.
