I imagine you have read something related to something called EUROCALL or CALICO in the introductory chapter from your book. These are two of the most important CALL associations in the world. They have their own publications, annual conferences, SIG (Special Interest Groups), newsletters, etc, in the same way other professional associations do.
The first one, EUROCALL stands for European Association for Computer-Assisted Language Learning and it is the main authority of CALL in this continent.

EUROCALL has also a relevant publication, called ReCall.
CALICO is the equivalent in the American continent.
