|The Bosses' Songbook|
SDS (Students for a Democratic Society) has a website. They have links to The Bosses' Songbook, but they go nowhere.
Several places are willing to sell you a copy of The Bosses' Songbook, Amazon has the low, low price of $100. You can get a electronic copy of the Little Red Songbook from Google Play for cheap, or you can buy an original via Amazon for something over two grand.
