Buy books. But not from Amazon. Buy them from Bookshop.org, the independent site. This move by Amazon is shameful.

Here is a link to my book on Bookshop.org.

@petergleick Worth adding, for those not already aware, that Bookshop.org lets you contribute part of your purchase to a local bookshop of your choice, and that they've recently started selling eBooks as well. And the digital sales can support local shops too!
