Is a new site which I have recently discovered and decided to join. This from their introduction:
"Books4Spain has been established by Rod Younger, an Anglo-Spaniard and author, to help you discover Spain and its rich history and culture through books, as well as to provide you access to useful, relevant and interesting information about living, travelling or holidaying in Spain.
Our intention is to try and re-create the experience, attractions and benefits of a traditional bricks & mortar independent bookshop but with the added convenience afforded by the Internet and technology to offer better choice, an easier way to discover books about Spain, great customer service and, ultimately, to enable our clients to learn more about Spain, its culture and history."
So take a look, maybe buy some books and add some reviews.
