http://www.numibooks.com/ looks like it would be a useful site if people actually used it. Site seems like a ghost town, although someone went to the trouble to put a lot of book information in.
Google has a feature (part of Advanced Search) that reveals who links to a web page. According to Google, only numibooks.com links to the numibooks main page.
I was wondering how the site was doing and tried searching for it but had a hard time finding it. I couldn't remember the name and searching on terms like 'numismatic', 'book', 'review' didn't help.
I don't know if the site is a labour of love by some collector or just a way to harvest Amazon referral money.
I still haven't found an Internet replacement for my trusty copy of Kroh's Ancient Coin Reference Reviews. At $25, this is one of the bargains of ancient numismatics.
