Daniel Singer wrote a great book for Monthly Review Press in '80 on Solidarity. First chapter is a useful critique of Solzhenitsyn, btw.
Do a google, "Pugilese Solidarity Poland, " and you'll probably find a bibliography I did for John Lacny's marxist at yahoogroups.com list a few yrs. ago for sources on Solidarity mostly by academic leftists like the fellow who wrote, "The Populist Moment, " who wrote on Solidarity. Off the top of my head look up David Ost, back issues of Labour Focus on Eastern Europe, a special issue of Telos, "Solidarity and the Future of Socialism, " with pieces by Jadwiga Stanzikas (may be off on the spelling, she wrote a book for Harvard U. Press on Solidarity), Jacek Kuron (co-author of a famous open letter to the Polish CP in the late 60's that Western Trotskyists translated), Adam Michnik, Stan Persky, the New Yorker writer, Lawrence ?.
Solidarity, had many currents from neo-trotskyist, catholic left to anti-semitic right. By coincidence last night looking at Grover Furr website I skimmed a little of his Maoist denunciation of Solidarity as just a bunch of CIA tools up to their necks in anti-semitism. Anyone who has seen, "Shoah, " by Claude Lanzmann or knows about the 1968 anti-semitic purge of the Polish CP (Polish United Workers Party) knows that their is a deep current of anti-semitism.
