Marshall Sahlins, one of the most old school of the old school anthropologists, has taken to publishing the pamphlets of yore with the new twist of providing some of them on the web via his publishing company, Prickly Paradigm Press. Only the older ones are freely available on the web, but you can order any of them online. Take a look at the catalog. Interesting and available in PDF are:

Marshall Sahlins, Waiting for Foucault, Still

Bruno Latour, War of the Worlds: What About Peace?

Thomas Frank, New Consensus for Old: Cultural Studies from Left to Right
