Guardian article about academic publishing

I agree with a lot of this article in the Guardian. Especially:

Reading a single article published by one of Elsevier's journals will cost you $31.50. Springer charges €34.95, Wiley-Blackwell, $42. Read 10 and you pay 10 times. And the journals retain perpetual copyright. You want to read a letter printed in 1981? That'll be $31.50.

I get especially annoyed with the said letter was published in 1881, and therefore out of copyright yet they still charge you for it.
