In "Five Dozen Doctoral Students Chose Bits and Bytes over Ink and Paper," Kathleen J. Sullivan discusses Stanford University's ETD program.
Here's an excerpt:
Most of the Stanford graduate students who uploaded their dissertations—47 out of 60—chose to display their dissertations in their entirety.
Most of the students—52 out of 60—selected the "attribution non-commercial" license from Creative Commons. . . .
More than half of the doctoral students—36 out of 60—chose to release their dissertation immediately. Ten of them chose to delay the release for six months; nine chose a one-year embargo; five chose a two-year delay.
