I don&#x27;t buy as many physical books as I used to; mostly fiction, and mostly used.<p>I buy a fair number of ebooks, mostly technical, and mostly from O&#x27;Reilly. I love that they&#x27;re DRM-free; in my case I take the PDF version, but they have other formats.<p>Pakt has a very low-intrusiveness form of &quot;DRM.&quot; They print your name on every page of the pdf that you buy, but it&#x27;s otherwise unrestricted.<p>I don&#x27;t think Pakt or O&#x27;Reilly is going to come after you for sharing an ebook with a family member, and I&#x27;ve given a few copies of O&#x27;Reilly books to colleagues, to evangelize both O&#x27;Reilly and the tech in question.
