I've stumbled across references to the Dictionary of Christian Antiquities (edited by William Smith and Samuel Cheetham) in a PB I'm working on, and I'd really like to have it so I could make cross-references to it. It's almost up to 60% and it's going for only $12, with a gentle slope leading up to that, which means we'll probably be able to get it down to maybe $8 after it crosses the line.
This looks like a really excellent resource, for a very good price! Its longer title is A Dictionary of Christian Antiquities, Being A Continuation of 'The Dictionary of the Bible' (you know Smith's Bible Dictionary, which is already available in Logos? this is a continuation of that, so it would be good to have it in Logos)
It's available for perusing in images on the Internet Archive, but wouldn't it be valuable to have this within Logos, and be able to look things up in it easily, link it to other books, copy/paste text from it, etc.?
Here are some sample pages, giving you an idea of how in-depth it is; this is the article on "Bishop" (33 pages!). If you ever wanted to do research on the office of bishop in the ancient church, you're not going to find any resource that gives you more information than this!

















So don't delay. Go bid on it here: http://www.logos.com/product/15500/dictionary-of-christian-antiquities
