Editing Edsger W. Dijkstra (section)

=== EWDs ===
Dijkstra was well known for his habit of carefully composing manuscripts with his [[fountain pen]]. The manuscripts are called EWDs, since Dijkstra numbered them with ''EWD'', his initials, as a prefix. According to Dijkstra himself, the EWDs started when he moved from the Mathematical Centre in [[Amsterdam]] to the Eindhoven University of Technology (then Technische Hogeschool Eindhoven). After going to [[Eindhoven]], Dijkstra experienced a [[writer's block]] for more than a year. He distributed photocopies of a new EWD among his colleagues. Many recipients photocopied and forwarded their copies, so the EWDs spread throughout the international computer science community. The topics were computer science and mathematics, and included trip reports, letters, and speeches. These short articles span a period of 40 years. Almost all EWDs appearing after 1972 were hand-written. They are rarely longer than 15 pages and are consecutively numbered. The last one, No. 1318, is from 14 April 2002. Within computer science they are known as the EWD reports, or, simply the EWDs. More than 1300 EWDs have been scanned, with a growing number transcribed to facilitate search, and are available online at the Dijkstra archive of the University of Texas.<ref>{{cite web |website=E.
