If you are like me, you may find quite strange that a website that speaks about "accessibilty" doesn't share its content via HTML. Yeah, this is possible on the accessibility checklist website itself (!), where the documents are available in MS Office and OpenDocument format. Even a zip containing all files is available, but the documents are not available in PDF or even worse, in HTML.
HTML is the most accessible format, because it can be opened in any browser, doesn't need any special plugin or external program (both word and openoffice formats need a program installed, to be viewed).
I like HTML because I can also view/read it -if coded well- in a window that fits my needs. With a so called responsive design a website can work on any width and height, especially when we talk about a simple text to read or even an e-book. I don't like PDFs because the format is given and generally it can't be scaled, unless the PDF reader is really smart and allows so.
What I did was simply download the doc files and export them as html with Word 2013 and share them here. It costed me about half an hour. Hopefully it can be helpful for other people. Maybe you can add the checklist or the explanations in your "read later" list on Instapaper, enjoy!
