Summary
FSI is an acronym for the Foreign Service Institute, "the (US) Federal Government's primary training institution for officers and support personnel of the U.S. foreign affairs community".
Over the years, the FSI has researched, designed and taught language courses to Foreign Service staff and diplomats. These courses are now available and licensed to the Public Domain.
FSI-Language-Courses.org is a sweet and simple website that provides users with the ability to view and download the Foreign Service Institute's courses for 31+ languages. The content is provided by individuals donating time and resources in an overall effort to provide quality languages-learning materials for free worldwide.
Sounds good to me. :)
In the Spanish section of the site, there is currently one volume of a Spanish Basic Course and two volumes of a Spanish Programmatic Course. These courses give total beginners a solid and useful introduction to practical situations that you actually encounter in your average day while traveling, studying or working in Spain or Latin America.
