In an attempt to promote his work A Treatise on Human Nature (1738), David Hume anonymously wrote and in 1740 had published a booklet, An Abstract of a Book Lately Published, Entituled, A Treatiſe of Human Nature, &c. It went nearly unnoticed and unrecognized until republished in 1938, with an introduction by John Maynard Keynes and Piero Sraffa. That edition was reprinted in 1965. The introduction may still be protected by copyright, as may be images of the reset text.
In any event, I did not find any editions of the booklet itself freely available on-line; so I have created one.
Well, actually, two editions. The first retains the use of long ess (‘ſ’) and the convention by which longer passages were quoted, which was a matter of prefixing a quotation mark to each line which continued a quotation from the previous line. The second replaces the long esses with now ordinary lower-case esses, and uses block quotation where now conventional, though the second version otherwise preserves the spelling and punctuation of the original.
The Abstract is about 6,500 words. The booklet was just thirty two pages, one of which was a title page and one of which was blank. My transcriptions come each to less than nine pages of twelve-point type.
Addendum (2017:12/15): After I posted my transcriptions, a Google search on an Android tablet returned a link not previously returned by a Google search on my Linux box, to a transcription by Carl Mickelsen lacking the original preface contained in the booklet, and with the remaining text extensively editted to change spellings, punctuation, italicization, &c I also found a wholesale paraphasing of the Abstract by Jonathan Bennett, with changes far more extensive than the reader is led to believe
