Internet: Information free and payed

Also what I noticed while watching the movie Resolved 2007 was that lots of debaters accessed databases of journals etc. which require subscription fee like EBSCO, Project Muse, Lexis-Nexis etc. to acquire solid material for debate.  Which reminded me of my own search of material at home. Usually I do search information at a PC on my university this grants me (unknowingly) access to most databases of journals the university is subscribed too.  But when I do some late night searching on my home PC, I stumble upon not accessible papers even via Google but more via specialist databases of journals.

I am still not sure if this divide in free and paid knowledge is appropriate for the internet.  I am leaning  towards initatives like arXiv which is based on the open acces movement .
