Reading a scholarly article effectively is quite different than how you would read a novel. Most novels are intended to be read as a whole, front to back. Scholarly articles on the other hand are meant to be dissected like a pie into many different pieces, such as an Abstract, Discussion or Methods section. Skipping around in a novel would be a little confusing, but it's encouraged when reading a scholarly article.
