Tired of looking through listings to find what you want? Try the Ada-on-the-web search engine, which searches more than 200 sites and parts of sites devoted to the Ada Programming Language, without mixing in results for other languages, dairy farmers, dentists, and disabled people, or missing results because of very specific queries.

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.
