This Unesco report (from 2008) has a succinct definition of information literacy that has to do with people's capacity rather than specific rules:
"Recognise their information needs;
Locate and evaluate the quality of information;
Store and retrieve information;
Make effective and ethical use of information, and
Apply information to create and communicate knowledge."
Information literacy (as noted here and in the digital cultures master's module) doesn't just apply to one context, when using a computer for example, it's applicable throughout contexts and I think that's what defines capacity as literacy - readers/users can move through a variety of contexts (much like transliteracy). "IL skills are necessary for people to be effective lifelong learners and to contribute in knowledge societies."
These elements of information literacy say it all - they cross contexts:
"a. Recognise information needs
b. Locate and evaluate the quality of information
c. Store and Retrieve information
d. Make effective and ethical use of information, and
e. Apply information to create and communicate knowledge."
