Okay, first week, first book - even if that should have been twenty days ago!
I'm going to start with an odd one - just as I probably intend to continue. I picked up a copy of Brewer's Britain and Ireland, a compendium of etymologoes for 7500 placenames in Britain and Ireland. Fabulous thing!
I will say one thing about the books I add over the coming weeks. This is likely to not be the last reference title I add to this list. I have to admit a certain addiction to reference titles.
Anyway here's a couple of links in case you want to go buy it (Amazon's UK and US)
