An article by Joyce Priddy summarizes in a recent article on the value of online libraries.

She is surprised on the number and varieties of libraries that are now online. But as readers of this blog know, this should not be. With the cost of copying and putting books online decreasing, it will only be a matter of time before all books are put online ....... and if I should be so bold ...... they will be free, with revenue sources coming via through advertising and/or other revenue generating sources.
