Bogleheads:Copyrights

The Bogleheads Wiki employs the GNU Free Documentation License, Version 1.2, a "copyleft" arrangement. From the Wikipedia article on Copyleft,

''Copyleft is a form of licensing and may be used to modify copyrights for works such as computer software, documents, music, and art. In general, copyright law allows an author to prohibit others from reproducing, adapting, or distributing copies of the author's work. In contrast, an author may, through a copyleft licensing scheme, give every person who receives a copy of a work permission to reproduce, adapt or distribute the work as long as any resulting copies or adaptations are also bound by the same copyleft licensing scheme.''

A caution is in order for prospective authors of traditional financial publications. It is not acceptable to write an article on the Bogleheads Wiki and then incorporate it into a copyrighted work.
