PLUS, if we can get 7000 people to subscribe, then we won’t need to show ads at all. You can be one of them, and your subscription will help people who can’t afford subscriptions to be free from the ads too! People living in poverty all over the world rely on the Internet for their library resources, and we’d much rather be able to bring them their information free of ads. Can you help us get there?

Your password will be good for a year, and then you’ll automatically be unsubscribed. No tricky surprise charges, no automatic renewal (don’t you hate that?). In less than a minute, you can be a premier user of Quatr.us.

You don’t need a subscription? Please consider making a small donation to Quatr.us, to help us reach our goal. Most people donate $20, but any amount is welcome!

 

We’ve worked hard to build Quatr.us – it’s taken us twenty years to put together the three thousand pages and about ten thousand pictures and diagrams on this site. We go over all the pages at least once a year to update them with new discoveries and include recommendations to up to date books. We are constantly redesigning the website so you can search better, surf Quatr.us on your phone better, and just find things more efficiently. Quatr.us is free to everyone all over the world, and people use it in every country in the world. Even small donations really help! Big donations help more!
