How To Determine CI version

[eluser]Unknown[/eluser]
Hello - newbie here
I have inherited someone else's abortion and am not familiar enough with CI to find its version number. Is there a straight forward way to do this?

Sure, it's defined at the top of /system/core/CodeIgniter.php

You can "echo CI_VERSION;" from a controller to see it as well.

Thanks! At least now I can proceed with the learning process - any good books out there?

If you are done with PHP, user guide is good starting point.

I agree with above comment;
