I downloaded a total of 25 items: 16 from MR (including 8 omnibuses), 7 from Smashwords and 2 from Feedbooks.
One was a short story. I figure the omnibuses average 6 books each. So without going over each to calculate the total, I figure I downloaded 64 books.
I doubt that I will read every book of every omnibus, but I'm confident that I'll read at least the first each, and therefore at least 25 of the total.
