To all our users in the United States,
Today, we ask you to help Open Knowledge Maps. As a charitable non-profit, we depend on community support. This is why we have started our first donation campaign.

If everyone reading this gave $3, we could run Open Knowledge Maps for a full year.

Open Knowledge Maps is the largest visual search engine for scientific knowledge. Our open, ad-free service is used by hundreds of thousands of people around the world. With your help, we can not only keep Open Knowledge Maps online, but also develop it further.

We hope that you'll consider how useful it is to be able to discover scientific knowledge. Not only for a select few, but for everyone on the planet. The price of a coffee is all it takes!

Thank you. - Peter, Maxi and Chris from the Open Knowledge Maps board
