MIT's intro systems class has a bunch of the same papers, and some other good ones people might like. The list is http://web.mit.edu/6.033/www/reference.shtml but you can find links to the papers through the schedule at http://web.mit.edu/6.033/www/schedule.shtml

Just FYI, some (but not all) of the items linked from schedule.shtml are restricted content. E.g.

"Preparation: Read Simon paper"

...

"This paper requires an MIT personal certificate for access: The Architecture of Complexity"
