Study of Business Models

So I became curious on the subject of business models, for example, are there a bunch of business models that exist that one can study? After some Googling, I did not see all that much, however I discovered this academic study, which according to it, despite being talked about all the time, there isn't a whole lot of formal study it seems on the subject of business models: Do Some Business Models Perform Better Than Others?

It seems that the subject of business models is like the subject of building business systems to automate one's business, i.e. a very important subject, but one in which there is not much formal information about. I think it would be interesting is maybe someone could write a book or two on this subject, as an academic reference, as it could be very handy for entrepreneurs trying to get started. As Michael Gerber points out in his book "The E-Myth" (now "The E-Myth Revisited"), most people who start businesses don't start them for entrepreneurial purposes, they start them for totally different reasons, which is why so many businesses fail and why those that succeed, the owner often finds that in their quest for freedom, to be their own boss, that they have in effect bought themselves a job, because they had no idea about systemizing the business so that it can operate independently of themselves.

All people who start a business with the mindset of an entrepreneur know that one must build business systems, but how to go about doing that, I don't think there is much in the way of formal knowledge.
