Магазин электрических книжек O'Reilly — фсе ( Пестуйте, грят в амазоны, а лучше — в подписку сафари за каких-то жалких 100-500 уе в год:
Things are changing at the O'Reilly online shop—as of today, we are no longer selling individual books and videos via shop.oreilly.com. Of course, we'll continue to publish books and videos on the topics you need to know, like data science, product management, and leadership—and you'll still be able to buy them at Amazon and other retailers. And these important things about your O'Reilly account are staying exactly the same:
You'll still have access to every ebook and video listed in "Your Products" on your O'Reilly account page.
We'll alert you when those products are updated, and you can download the revised version from the "Your Products" page.
You can still send the O'Reilly ebooks you've purchased to Dropbox and/or Google Drive.
Of course, every O'Reilly book and video (including O'Reilly conference sessions) is available instantly on Safari...
подписка в сафари — огонь, рекомендую.
