George Sale's version of the Qur'án I typed from the original print versions (from the 1800's and early 1900's - different editions had different materials which I discovered at different stages, so I used several editions to include all of the items). Rodwell's version of the Qur'án was based on a Project Gutenberg online text to which I added a Suráh that had been missed (at the time) and some other corrections and notes. -B.Z.
The Sale translation is available for purchase but please be aware that the print is very small, due to limitations faced by the publisher in preserving the original pagination (important since the original version had no verses).
Other online versions are at archive.org (PDF of 1877 edition) and gutenberg.org (html version no footnotes).
