From their own words:
A Living Pocketbook of Neurology
Applied, Concise, Practical, Up-to-Date, Mobile-Friendly, Peer-Reviewed & Open-Access Pocketbook of Neurology and related clinical specialties
The amazing thing about this pocketbook is that the content on this website is written by more than 60 authors. It’s a multinational and joint effort of so many authors. They are all collaborating and making use of Notion’s permission/access features very effectively.
They even have a discord channel where they interact with each other about this. Each author gets their own page on the website where they can share and maintain their own presence on the internet. I am really impressed with how much they were able to achieve.
They have authored around 50 chapters and they said they will be adding 50 more chapters soon. You should definitely check it out to see the power of Notion (combined with MDX.one). It’s amazing!
