Bookshop.orgβ β β β βA good place to shop online for books and still support indie bookstores. They sell eBooks too, in standard ePub format.
BOOX Go 7 Color (Gen II)β β β β β After five years, I replaced the Poke3 with the Go 7 Color. Itβs a lot faster and more responsive, brings back physical page turning buttons, and adds (pastel) color. Like its predecessor it has a sharp e-ink screen and runs any Android-based ebook reader app.
eBooks.comβ β β β βAn eBook seller with some actual business ethics. No hardware (which simplifies things), but they have an app for Android and iOS, and any DRM-free titles can be downloaded and read on just about anything.
Onyx BOOX Poke3β β β β βI used the Poke3 as my main ebook reader for almost five years. Itβs a convenient size, has a clear e-ink display, and can run the Android app for (almost) any eBook store.
Project Gutenbergβ β β β β Predating the web itself, theyβve put together tens of thousands of ebooks from classics and other public domain sources in multiple formats from plaintext to ePub.
Standard Ebooksβ β β β β Great source of classics and other public domain material, formatted and edited for maximum readability and compatibility.
