I went perusing through google books today looking for some old information. Found six books with limited or unlimited previews available to the online reader.
I read through the history of the Michigan baseball team. It was rather interesting. I found an alumnus of my fraternity happened to be one of the two founders of the Michigan baseball program.
There were 3 baseball books, one track (the story of the quest for the sub four minute mile), one hockey, and one general sports (although its extremely limited in viewing ability).
Enjoy if you'd like:
If the link doesn't work, let me know in the comments. I saved them into my google library and I'm not sure how public that is as I'm too lazy to list each book individually.
