Library

The wishlist can be accessed here (and is progressively transferred there).
An open poll is about to be created in order to select the 50 or so most wanted books (first round) and involve the community in the action to make it happen, that is to get them. The crowdfunding campaign will take place on Open Collective.
DIY Book Scanner
https://www.diybookscanner.org/
The Archivist is the culmination of 6 years of scanner design. It allows you to make high quality scans quickly. The lighting is even with no glare and it is also great for color scans and glossy pictures. Daniel Reetz released the design of it into the public domain so you can look through his complete design guide and build one yourself from scratch.
Standard ebooks
https://standardebooks.org/about
Free and liberated ebooks, carefully produced for the true book lover.
The Standard Ebooks project is a volunteer driven, not-for-profit effort to produce a collection of high quality, carefully formatted, accessible, open source, and free public domain ebooks that meet or exceed the quality of commercially produced ebooks.
Inventaire
The Wikidata-federated open bibliographic database
The Inventaire project has two cores working in synergy:
A book sharing webapp, inviting everyone to make the inventory of their books, define what they want to do with it (giving, sharing, selling), as well as who should be able to see it (shared publicly, or only visible to your friends and groups).
An open data project aiming at building a CC0 Wikidata-centered database. It primarly aims to address the needs of the webapp, and is enriched by its users. More broadly it concretizes Inventaire mission: mapping resources with libre software and open knowledge, starting with books.
Translations
Thanks to a self-hosted instance of Weblate, we'll be able to achieve collective translations of those books, making good use of our local diversity of languages.
