E-book reference collection

I bang on a lot about e-books and how they mostly do good in the world.

But there's a collection of e-books that I quite often forget to mention. We have a general e-reference collection that is quite handy for researching the basics of a topic. Think of it as a reliable version of Wikipedia (although you do miss out on the fun of watching angry contributors slag each other off!) and that just about sums it up.

Anyhow. It's called Credo and it's pretty good if you're looking for definitions of ideas, theories or theorists within the social sciences sphere.
