The publisher is Ediciones Universidad de Navarra, Spain, and the name of the book in Spanish is "Romper el Circulo Vicioso". The website is:
www.eunsa.es but the e-mail information is not correct. The e-mail for order the BTVC in spanish from Spain is:
exportaciones@eunsa.e.telefonica.net
or: eunsaedi@abc.ibernet.com
or: eunsa@cin.es
or: eiunsa@ibernet.com
(contact to Mrs.Laura Huarte or Mrs.Beatriz Martinez)
Please send your order to all of this e-mails because for some reason they can´t recieve sometimes the information or call them because Beatriz Martinez, I supouse, knows the english language.

And here you could find other distributors from North and Latin America and the rest of Europe:
