This is a link to our local university's cooperative outreach program:
http://www.wisc.edu/uwcc/They have a nice page of all-around coop news and information (not just from WI).
The 'information by topic' and 'information by sector' have loads of links, articles, and papers on various cooperative issues encompassing worker, consumer, and supplier coops.
Of course, no informational post on coops would be complete without a recitation of the Rochedale principles.
As one source says:
In 1844 a group of 28 weavers, today known as the 'Rochedale
Pioneers', started a shop in the small town of Rochedale in England.
This group are attributed with the origin of the co-op philosophy
--------------------------------------------------------
The Rochedale Cooperative Principles1st Principle: Voluntary and Open MembershipCo-operatives are voluntary organisations, open to all persons
able to use their services and willing to accept the
responsibilities of membership, without gender, social,
racial, political, or religious discrimination.
2nd Principle: Democratic Member ControlCo-operatives are democratic organisations controlled by their
members, who actively participate in setting their policies
and making decisions. Men and women serving as elected
representatives are accountable to the membership. In primary
co-operatives members have equal voting rights (one member,
one vote), and co-operatives at other levels are also
organised in a democratic manner.
3rd Principle: Member Economic ParticipationMembers contribute equitably to, and democratically control,
the capital of their co-operative. At least part of that
capital is usually the common property of the co-operative.
Members usually receive limited compensation, if any, on
capital subscribed as a condition of membership. Members
allocate surpluses for any or all of the following purposes:
developing their co-operative, possibly by setting up
reserves, part of which at least would be indivisible;
benefiting members in proportion to their transactions with
the co-operative; and supporting other activities approved by
the membership.
4th Principle: Autonomy and IndependenceCo-operatives are autonomous, self-help organisations
controlled by their members. If they enter into agreements
with other organisations, including governments, or raise
capital from external sources, they do so on terms that ensure
democratic control by their members and maintain their
co-operative autonomy.
5th Principle: Education, Training and InformationCo-operatives provide education and training for their
members, elected representatives, managers, and employees so
they can contribute effectively to the development of their
co-operatives. They inform the general public - particularly
young people and opinion leaders - about the nature and
benefits of co-operation.
6th Principle: Co-operation Among Co-operativesCo-operatives serve their members most effectively and
strengthen the co-operative movement by working together
through local, national, regional, and international
structures.
7th Principle: Concern for CommunityCo-operatives work for the sustainable development of their
communities through policies approved by their members.
--------------------------------------------------------
Finally, note that specific laws governing cooperatives are a state-level issue, and that each state has slightly different laws regarding the formation of a cooperative.

I just realized that by posting this, I'm upholding the 5th Cooperative Principle. :)
