Here is a great article about Slow Reading: http://www.gnn.com/article/slow-down-you-read-too-fast-is-the/1122324?icid=sphere_wpcom_inline/

I agree with a lot of the points made in the article and think that people need to start reading with comprehension and retention as their goals. Hopefully people will be able to recall what they understood in the literature. Too often, people are just trying to get through it as quickly as possible.
