Ada Learning Materials

The AdaIC site collects a wide variety of materials and information useful for learning Ada. Beyond the usual collection of printed books for every modern version of Ada, we also have a variety of electronic books, electronic tutorials, social media sites for answers to specific questions, Ada-related websites, information on professional Ada training, and even a list of schools that use Ada in their curriculum. Check it out in our Learn Ada section.

Organizations Focused on Ada

A variety of organizations focused on Ada are available. All have something to offer to the Ada user.

The two large regional organizations both sponsor conferences and have well-regarded newsletters. ACM SIGAda (Special Interest Group on Ada) in North America and Ada-Europe are definitely worth supporting.

There are also a variety of national and local organizations, see our Ada Associations page for more information.

We'd be remiss to forget the Ada Resource Association, the sponsor of this web site. The ARA undertakes projects to promote the growth and use of Ada. Find out more on our ARA community page.
