What is being featured represents the next chapter in the publishing house's history.
From Greenleaf's website:
Modern Greenleaf Classics Books
1976 - 1990
By 1976, the original management team was gone and the books changed their character. The pool of writers changed. The staff of cover artists changed. The editorial team that set story policy changed. Earlier imprints were halted and new imprints started. Thus the distinction being made here between the vintage and modern periods in the archive.
The books from the Modern period cover a wide spectrum of specific fetish themes featured in the various imprints. The cover art is either colorful and striking or simple line drawings illustrating a narrative scene.
I am not sure if today's covers are part of the next generation of Greenleaf Classics. But they are not listed among the Classic period's (1959-1975) imprints, though the publication dates typically assigned are 1969/1970. They include a number of re-issues and a few of the authors should be familiar to you.
'The American people want sexually oriented material,' Hamling tells the New York Times. 'This is what's on the best-sellers' list, and now the best movies are those rated R and X (Midnight Cowboy's original rating). The people have mandated for explicit sex. The snowball has started and that's why this trial is so important.' (New York Times, November 1971)
Judge Thompson admits that he is 'overwhelmed.' His first big case since taking the bench, he is, reportedly, under a great deal of pressure from Attorney General Mitchell and the Justice Department to assure convictions. The judge vehemently denies this, but reliable sources insist that there was a mole in Judge Thompson's office reporting to the defense who swears that the judge was receiving phone calls from the Justice Department on almost a daily basis to check in on the trial's progress. I have not, however, been able to confirm these reports with substantiating evidence.
In a scholarly introduction, Douglas H. Gamlin, Ph.D. (Donald H. Gilmore, Ph.D.) compared the book to Spenser, Chaucer, et al, and hedged his bets by stating the writing suggests 'deep research on the part of the author or, indeed, that the author did exist four hundred years ago.'
Despite such a coy hint, Friar Peck quickly became accepted as an authentic piece of 16th century erotica, and still appears as such in book catalogs. So I did make a contribution to the literature of the Dark Ages, although I'm not quite old enough to have lived through them."
And one more interesting tidbit: Greenleaf Classics invested in a number of feature-length adult films. Most notable among them being Adultery For Fun And Profit, an award-winner at the 1970 Amsterdam sex film festival.
