"This document was released only to a select number of existing customers of the company SirsiDynix, a proprietary library automation software vendor. According to our source it has not been released more broadly specifically because of the misinformation about open source software and possible libel per se against certain competitors contained therein."
This has caused a great deal of debate with Stephen Abraham (vice president of Innovation for Sirsi Dynix) writing in a blog post entitled it's about a respectful discussion. On the other side we have Meredith Farkas looking at the subject of open source and the part of vendors in the library role. Her discussion is well more interesting look at things.
