Changes to Keith Shaw's Talk to the EMFSO on best design practices. A must read!
Keith's original article/talk, as posted on the EFO site for a long time, was split into four parts to be sure that it would fit on floppy disks.
Patrick Surry has combined the original four parts into one. The whole article as one .pdf file.
He also made a version to view on a phone, Kindle, etc. updated 11/01/12
