How? I just bought "You don't know JS: Up and Going" (only $5, so not bad as a test) and I was prompted to download Google Books.

I have stopped buying Kindle books due to no longer being able to back up the files (KFX switched to a new encryption type). I rarely buy technical books, but O'Reilly was my go-to due to actually being able to have the real files offline.

Edit: Okay, Google don't make it easy and there's no way to do it from Android. Go to https://books.google.com.au/books and click on a book in your library. If the publisher has allowed it, there'll be a cog in the upper right corner that will have "Download PDF" and "Download EPUB" available.

Its amazing that a company whose main product is search has such a worthless search for their store. Its absolutely worthless unless you already know exactly what you want.

You have to use their general search product to find enough info to bring up the exact title you want to buy.

For example you can't on the play store find all the oreilly books that aren't drm encumbered or find all the books on a certain topic in a certain range of years directly via its interface.

Does it have the same pricing as O'Reilly's online store did? Heavy discounts (60%+) for multiple book purchases over $100? Early access books? What about .mobi? (I still have some actual eInk Kindles including the original DX!)

O'Reilly themselves say Google play only offers epub, I think they've killed PDF there too
