Open Loops has a great post called A Quick and Dirty Reading Strategy When Time is Short.
“The first thing that one has to realize is that all reading is not the same. Reports are written for a different purpose than articles. Articles are written for a different purpose than letters. Letters are written for a different purpose than proposals. Yet, most of us try to read all types of reading materials the same way. The first rule of plowing through reading materials is realizing that some material deserves a thorough and precise reading and some does not. DonÃ¢â‚¬â„¢t feel guilty in not giving some material deep attention if it doesnÃ¢â‚¬â„¢t deserve it.”
This is a great idea on how to save time and keep up.
