The Association of College and Research Libraries' Framework for Information Literacy for Higher Education provides six frames to guide library instruction programs. (The frames are listed in alphabetic order; no ranking is meant.)
The Framework is available free online.
The Association of College and Research Libraries (ACRL) defines Information Literacy as "the set of integrated abilities encompassing the reflective discovery of information, the understanding of how information is produced and valued, and the use of information in creating new knowledge and participating ethically in communities of learning."
