If you're super-interested, you might want to check out ARMA (American Records Management Association) and the Association of Canadian Archivists (http://www.archivists.ca/), too.
jadelennox is right -- the archival profession's been changing incredibly quickly and in profound ways with the digital age (even if you're only looking at the practical aspects, digital formats require completely different preservation techniques), and there are all kinds of issues of intellectual property, authenticity, privacy, etc. that are being re-evaluated.
In light of the actual topic at hand -- one of the issues with state archives is that appraisal (the decision process re: the value of documents and what information needs to be preserved) is not as objective and neutral a process as people would like to think. Certain kinds of records and certain kinds of record creators are more likely to be dismissed or preserved than others, and simply being in the position to make those decisions gives people a very real kind of cultural power in a historical big picture sense.
