One of my side projects is Ethical Book Search (https://www.ethicalbooksearch.com/), a site which makes it easy to find more responsible alternatives to Amazon when buying books online.
The site is supported by affiliate revenue, half of which is donated to charity and the other half pays for hosting.
This year we've been able to give over £300 to Room To Read (https://www.roomtoread.org/) and over £100 to The Internet Archive (https://archive.org/)
Thanks for all your support through the year.
