Where can I find a text book about Spanish law in Spanish?
Try searching for books on law using the Spanish language itself. You might have tried that already, but a native Spanish speaker will probably look for law textbooks in his or her native language, and they’ll probably be more likely to pop up that way. I translated an English phrase into Spanish using translate.google.com (because my Spanish isn’t that great), and then I searched Amazon.com with the phrase copied from Google Translate. I was able to find this book: http://www.amazon.com/Generales-Ordenamiento-Financiero-Tributario-Biblioteca/dp/8430949275/ref=sr_1_fkmr2_2?ie=UTF8&qid=1301522162&sr=8-2-fkmr2 Google translates the title as General Laws Spanish Financial and Tax Ordinance / General Laws of The Spanish Financial and Tax Ordinance (Legal Texts Library / Legal Texts Library) (Spanish Edition). I don’t know how accurate that translation is. You probably want more of a general law book than a law book on taxes, but it’s a start.
I assume you’ve tried googling for courses of study at Spanish law schools? My Spanish is incredibly rudimentary and I’ve given up trying to find descriptions of such courses, which would probably list assigned texts. You might be able to find something here: http://www.amazon.com/b/ref=bw_ab_301731… I suspect you’d be more likely to get Latin American than Spanish books there, though, and I’m not at all sure that law textbooks in languages other than English would even be carried by Amazon.com. However, I’m sure there is at least one internet bookseller that serves Spanish customers and more that serve Latin American customers. (I’m not convinced that either amazon.fr or amazon.de is such a bookstore, but they might be.) Pay careful attention to shipping costs if you’re going to or
