uh, if i read your question as "what an anarchist society *could* look like", and ignore the loaded terminology of institutions, then i can suggest bolo bolo by pm, which is expected to be back in print in a couple of months.
there is also The Dispossessed (or Always Coming Home) by leguin, of course.
if you meant some text that is not (science) fiction, then i have nothing for you.
edit: for a good survey of some utopian fiction, done by anarchist Marie Louise Berneri (yay!), read Journey through Utopia.
