Libraries of Things


Libraries of things give us access to items such as kitchen appliances, tools, electronics, toys & games, musical instruments, art, science, craft, gardening & recreational equipment, and much more without having to buy. All via an online catalogue.

They help create a society where resources are abundant because they are shared. They also encourage the reuse and repair of products, which improves the social and economic efficiency of our communities.

LoTs can be generic or specialized. Like a book library, you sign up as a member and start using the service.


Launching the first Library of Things in Barcelona on January 23rd 2020.
