Both The Artifact Competition and The Gun Golems have had cosmetic overhauls, giving all three books a more consistent look. One of the main things I did was convert the straight quotes to smart quotes (it's such a simple fix, but I know more now than I did a year ago). Anyway, both volumes should be somewhat prettier now.
I don't mean for this to be a crutch or a substitute for doing my own proofreading, but if anyone has found errors (spelling, typos, etc.) in any of the Approaching Infinity volumes, please let me know.
Thanks and Happy New Year!
