Open Source Licensing (Score 1)

For those wishing to understand the differences between open source licenses, I recommend the book "Open Source Licensing" by lawyer Lawrence Rosen (it is also available online at http://www.rosenlaw.com/oslbook.htm). There is also an interesting discussion on this topic summarized here http://wiki.na-mic.org/Wiki/index.php/NAMIC_Wiki:C ommunity_Licensing.
