Dijkstra Archive (1930-2002)
Although most of Dijkstra’s publications began life as EWD manuscripts, the great majority of his manuscripts remain unpublished. To alleviate both of these problems, the department has collected over a thousand of the manuscripts in this permanent web site, in the form of PDF bitmap documents (to read them, you’ll need a copy of Acrobat Reader). When Dijkstra himself didn’t provide the backward references, we indicate the relationship by “see also” links in the index, leaving the judgment of the extent to which the earlier EWD is superseded by the later one to the reader.
