There aren't any articles I can point you to, but I live in Portland, Ore., and between here and Vancouver and Camas, WA, there are a number of collectives that are doing exactly this. They don't publicize, it is word of mouth. They primarily focus on raising chickens and pigs, and butchering them for the members. All members participate somehow. Some members host the animals, others who cannot, contribute for feed and vet bills or participate in the slaughter days since it is a lot of work a few times a year.
They are successful but are not capable of replacing 100% of the grocery needs. And vegetables only appear in the summer and can be subject to infestations or random die offs... although there is significant canning that takes place throughout the summer for the winter months. Growing a diverse amount vegetables to support 25-50 people is surprisingly more complex than raising livestock (unless you just want to eat lots of zucchini and squash ;-).
However, there are many well documented small co-ops in Portland that I can refer you to if you want to ask them questions. These are very small farms, and in many cases people buy their shares of well in advance, and some have even become store-fronts rather than pickups.
Here are examples of places within a 15 minute drive of where I live:
When I used to eat meat I would buy half a cow with some friends friends. You could go visit the cow throughout the year:

This place exploded in popularity in the past 7 years. It used to be two guys and you would order chickens months in advance and pick them up a day after the slaughter, now I can just walk into their store and they have a growing staff:

This dairy was a kickstarter, and I get milk, cream, and eggs from them year round, its fantastic.

Lastly, Sauvie Island just outside portland has an enormous farm community where half of the year one can purchase all manner of fruits vegetables through multiple farmers market stands.
Again though: it is only for part of the year, year round veggies are damn hard without large industrial apparatus. Unless you like pickled things.
It can be done, but it takes a village. Seriously.
