Lightning Source got back to me and said that the hardback version of Eusebius, Gospel Problems and Solutions, should be available through Amazon in up to 15 days. This prompted me to look at the Amazon page, which revealed that two sellers were offering the book for sale! Most interesting!
One was Amazon itself; but the other was some bunch called “Winston bookstore UK”, offering the 50 GBP (=$75) book at 76.76 GBP. Apparently they have it in stock. No idea who these people are. But what they must be doing, I think, is importing from the US.
This made me look at the US Amazon, which has my book here as “In stock” (which it is) at $80. So … you can buy the thing in the US. This is very pleasing, since it’s how I intended it to work.
I haven’t been able to add any information to the Amazon listing, which is frustrating. My enquiries have been ignored. Not sure what to do next about that.
