"Prolog for Programmers"
Feliks Kluźniak & Stanisław Szpakowicz, with a contribution by Janusz S. Bień
Academic Press Inc. (London), 1987, ISBN 0-12-416521-4

First, with many, many, many thanks to Nate Craun,
here is a neat, compact, searchable version of the book, in PDF (3.11MB).
Just click on the happy face:
Prolog for Programmers
Now, the same as e-books (not searchable): EPUB (2.25MB) and AZW3 (2.21MB).
They were made from the compact file, so the quality is dodgy.
If you want a clean, readable version, sorry,
but you need the originally posted file, 47.28MB in PDF.
Click on the cover image. The file is large (and the server is slow), so try right-click or ctrl-click.
Or grab individual chapters — next page. Not searchable, sorry.
Finally, the larger e-books
(still not searchable, still on that slow server, still iffy quality):
EPUB (19.79MB) and AZW3 (19.82MB).
