Library 2.0 -- Like It Or Hate It, It's Public Domain
2006-05-26

O’Reilly has taken steps to consolidate use of the term “Web 2.0”, claiming it as a service mark. This has caused several worried library folk to contact me regarding “Library 2.0” and its usage. I first published the term “Library 2.0” in September of 2005. I have always considered the term “Library 2.0”, used alone or in combinations such as “Library 2.0 Conference”, to be in the public domain, usable by anyone, and not subject to trademark or service mark registration. I would hate to see this changed by anyone attempting to turn the term itself into a commercial venture. library2.0 web2.0
