Here are a few links to some of the texts discussed in the lecture and seminar today.
Firstly, this is a link to David Harvey's website which includes a series of lectures on Capital: http://davidharvey.org/reading-capital/
John also mentioned Michael Hardt's notes on Capital (Volumes 1 - 3), but I'm having trouble finding a readable version. This one seems to have lots of items that can't be displayed properly, so I'll have a look for a better version when I have time. http://www.duke.edu/~hardt/Capital.html
We also spoke briefly about the Francis Wheen 'biography' of Das Kapital, which may be of interest as regards considering Marx as a writer. Wheen argues that Capital is a gothic novel in this excerpt; if you like it, maybe track down the book itself. http://www.guardian.co.uk/books/2006/jul/08/politics
Also, John mentioned an essay by Nicole Pepperell called 'When is it Safe to ead Capital'. The essay looks at the first chapter of Capital in relation to Hegel's Phenomenology and Logic, and it can be found in the book of essays that he mentioned in the lecture. The essay is also available on Nicole's blog: http://www.roughtheory.org/content/when-is-it-safe-to-read-capital/
Finally, this text might be of interest in relation to the mode of presentation / mode of analysis ideas that we spoke about: http://www.marxists.org/archive/marx/works/1859/critique-pol-economy/appx1.htm (scroll down to section 3, entitled 'On the Method of Political Economy'). The analsysis / presentation issue is also raised in the afterword to the second German edition of Capital, which can be found in the Penguin edition. The relevant quotation is on p.102, but it's worth reading the whole thing (see in particular Marx's comment about 'coquetting' with Hegel on p.103).
