Almost all of Robbins' major works are available as Kindle eBooks. Amazon's proprietary format (.azw3) is not a standard PDF, but you can convert it using free software like Calibre. Prices range from $2.99 to $9.99. Check for "Harold Robbins: The Complete Collection" bundles, which occasionally go on sale.
Robbins pushed boundaries. In the 1950s and 60s, his books were banned in various countries and states for obscenity. Modern reprints sometimes soften the edge of controversial texts, or publishers might alter them for modern sensibilities. Dedicated fans often seek out original PDF scans to ensure they are reading the raw, unedited version that caused such a scandal in the swinging sixties. harold robbins books pdf
