There's no particular secret to it.
What I do myself is to find a page-scanned PDF of the book I want to proof, the older the better. "archive.org" is the best site I know of for getting these. Then, on my computer monitor I have the eBook and the PDF open side-by-side (you need a large wide-screen monitor to do this well) and I just read the two in parallel (this takes a bit of practice!). Whenever I find a mistake in the eBook I correct it there and then, and carry on. The end result is a hopefully well-formatted and error-free eBook.
This takes enormous concentration, and I try to spend about 2 or 3 ten minute sessions a day on it. I set myself a target of getting through perhaps 20 pages each day. That way, even the longest book I can get through in a few weeks.
It's very hard work, but I find it to be extremely satisfying, too.
