Do you read a lot and collect the books in a pile? Does it get expensive quickly when you buy new ones?
Here you can easily find a new book by checking out the users' ads on books. Just as easily, you post your own ad on your finished book to give someone else a chance to read it. Everything is free and the ads and books shouldn't cost anything, because reading is life and something that brings so much joy shouldn't cost anything. Shared joy is double joy, etc.!
Then, from an environmental point of view, you can also get some points on the karma account. Used is clearly a better choice most of the time. But mostly this app is about more people getting the joy of reading a book. Maybe a book you think is so great, that someone else likes less, while a third absolutely loves it. So let your book live a circular life instead of gathering dust on the shelf. Hope you like my virtual bookcase!
