Jonathan Packer's guide LIVE AND WORK IN SPAIN AND PORTUGAL is a book to steer clear of for those facing the challenge of moving to Spain. The book suffers from numerous problems.
LIVE AND WORK is first of all quite out of date. Although it was last updated in 1998, this update didn't change much from the original 1991 edition. As Spain is more and more integrated into the European Union, and the Euro is now the official currency, this guide's advice is often too old to be useful.
The layout of LIVE AND WORK makes the guide vexing to read. The text is often so compacted that it is difficult to see where one section ends and another begins. There are spelling mistakes here and there, and typesetting errors. The book also contains advertisements, which may disappoint those looking for independent advice.
Finally, this book is written for Britons who are thinking about moving to Spain and Portugal, for an American to learn about Spain and Portugal through this book, first one would have to be familiar with life in Britain.
If moving to Spain, I would suggest acquiring CULTURE SHOCK: SPAIN instead of this guide. It doesn't have nearly as many details, but it gives you an overview of the culture. One could augment that book with other resources that are up-to-date. All in all, however, it is best to avoid LIVE AND WORK IN SPAIN AND PORTUGAL.
