All information in Wikipedia must be sourced from elsewhere because it
must be verifiable. (see http://en.wikipedia.org/wiki/Wikipedia:Verifiability)
References should be to reputable sources, such as top newspapers etc.
There are guidelines ensuring that copyright material is not used
but in summary it seems that as long as an article is made of
information taken from many sources and written for Wikipedia and is
not cut and pasted from one source then it has been 'freed'.
It is then possible to take information from Wikipedia and reuse it
with acknowledgement as per the following:
"Permission to reproduce and modify text on Wikipedia has already been
granted to anyone anywhere by the authors of individual articles as
long as such reproduction and modification complies with licensing
terms (see below and Wikipedia:Mirrors and forks for specific terms).
Images may or may not permit reuse and modification; the conditions
for reproduction of each image should be individually checked. The
only exceptions are those cases in which editors have violated
Wikipedia policy by uploading copyrighted material without
authorization, or with copyright licensing terms which are
incompatible with those Wikipedia authors have applied to the rest of
Wikipedia content. While such material is present on the Wikipedia
(before it is detected and removed), it will be a copyright violation
to copy it. For permission to use it, one must contact the owner of
the copyright of the text or illustration in question; often, but not
always, this will be the original author.
