This handbook is unique in its focus on bilingual theories, issues on the teaching of bilinguals, bilingual policies abroad, and current research on bilinguals as all of this related in some way to the Spanish-speaking world. There is currently no other book like it available, despite the growing number of courses teaching Spanish Bilingualism. It is anticipated that this new handbook will be of great interest to linguists, sociolinguists, language acquisitionists, as well as teachers who deal with topics relating to bilingualism as it relates to Spanish speakers around the world. Though work has been done looking at bilingualism and multilingualism, this book provides a valuable addition that deals with an area where a comprehensive work such as this is indeed lacking.
