Why? Because it's a vast, almost limitless free library which provides me with books i'd never otherwise read.
Here's a new one: http://oll.libertyfund.org/titles/298
This will bring you George Bernard Shaw's FABIAN ESSAYS.
This has a really interesting feature .... an automatic link and citation for each paragraph in the document.
For instance:
http://oll.libertyfund.org/titles/298#Shaw_0066_24
and
George Bernard Shaw, Fabian Essays in Socialism, ed. G. Bernard Shaw, American Edition Ed. by H.G. Wilshire, (New York: The Homboldt Publishing Co., 1891). May 2, 2015. http://oll.libertyfund.org/titles/298#Shaw_0066_24
Neat little convenience.
I expect that all have been subject to my periodic rants on Fabian socialists aka progressives aka liberals. I expect when I wrap up Shaw's essays to produce a monster rant.
Maranatha,
