While appreciating the magnitude of the task keeping abreast of the flood of new cookbooks in English, have you ever considered listing non-Engish books?
Our library has a steadily increasing European section, mostly French, some Italian, the odd Spanish or German one.
In FNAC yesterday I had time to study the Cuisine section as was surprised (and disappointed) to see how many were devoted to cupcakes or macarons - or crumbles!!! This in the land of Brillat-Savarin and Curnonsky!
Sadly many of the really good ones just never get translated - La Mazille on Perigord is unequalled, in my opinion.
