Came across this book while surfing the 'Net for something entirely different. (Funny how that happens!)
Christmas in Ukraine: Christmas Around the World appears to be part of a series put out by World Book Encyclopedia.
Perhaps I should suggest it to Colby Cosh, since he was asking about Christmas in Ukraine on his blog last January ... but, being a freelance writer living in Edmonton, he probably has lots of sources close by to answer any questions. ;-)
