I am professional member of ACM
I few days back i became professional member of ACM. The membership for one year just costs $20.
As a member I got permanent ACM membership card. I also got access to a ebooks of Books24x7, safari books and Element K Courses and loads of other resources for professional as well as personality development.
Do become a member of this society; the resources are truly useful.
$20? How come ? Do you have access to their papers as well ?
