Affiliate Disclosure

en.popbook.com is supported by advertising and affiliate commissions. This page explains those relationships in full, as required by the US Federal Trade Commission and by the Amazon Associates Program.

The short version

As an Amazon Associate I earn from qualifying purchases. Some links on this site are affiliate links: if you click one and buy something, we may receive a small commission. You pay exactly the same price. Commission never changes which books we recommend, the order they appear in, or what we write about them.

Amazon Associates Program

en.popbook.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com and affiliated sites. Book links in the "Shop the classics" module, on book pages, in the gift guides and in reading lists may carry the tracking tag popbooken-20. Amazon may set a cookie to attribute a purchase; see our Privacy Policy for what that means and how to opt out.

We do not set prices, hold stock, take payment or handle returns. All purchases happen on Amazon's own site under Amazon's terms. No page on this site states a price or a discount, because we cannot verify either: an edition's price changes without notice and we do not track it.

Google AdSense and display advertising

We also display advertising served by Google AdSense. These ads are placed by third-party networks, which may use cookies to show ads based on previous visits to this or other sites. We do not endorse the products in those ads, and a click on an ad is not an endorsement by us. Visitors in the European Economic Area, the United Kingdom and Switzerland are shown a consent message from Google's certified consent-management platform before any advertising cookie is set, and can change that choice at any time. How to control personalised ads is explained in our Privacy Policy.

Editorial independence

Our reading lists are chosen for readers: public-domain status, literary value, availability of a lawful free edition, and the quality of the sources behind the notes. No payment from an advertiser or retailer buys a place in a list. Where a page contains a commercial link, it is labelled or accompanied by a disclosure on that page.

Free reading stays free

Every book we cover can be read free and lawfully through the public-domain archives linked from this site. Buying a printed copy is entirely optional and simply helps keep the lights on.
