# Personal Handbooks Personal Knowledge Bases allow compound learnings and make it easier to discover new abstractions or connections between concepts. Some interesting properties that a good Personal Knowledge Base should have: - Simple, Open Source and multi-platform. Works offline, uses plain text files, and has a backup mechanism similar to [[Git]]. - Focus on capturing ideas and content as fast as possible. - Should be managed as a graph: - Nodes are notes or smaller graphs. [Notes should be atomic, concept-oriented and densely linked](https://notes.andymatuschak.org/z4SDCZQeRo4xFEQ8H4qrSqd68ucpgE6LU155C). - Bidirectional links connecting nodes. - Nodes can have several parents (concepts). - Users can remix and connect ideas in multiple overlapping hierarchies. - [Each concept can be linked to external content (video, book, audio)](https://www.notion.so/Models-bb0f4bfd3cd140b3a00cd955e61003f9). - Content can have tags (related concepts) - Can be made public. - Personal Knowledge bases can be personal [ontologies with similar core components (individuals, classes, attributes, relations, ...)](https://en.wikipedia.org/wiki/Ontology_components). ## Open Source Projects - [Logseq](https://logseq.com/). - [Dendron](https://www.dendron.so/). - [Foam](https://foambubble.github.io/). - [Noosphere](https://github.com/subconsciousnetwork/noosphere) ## Handbooks - [Nikita Voloboev](https://github.com/nikitavoloboev/knowledge) - [Daryll Santos](https://github.com/daryllxd/lifelong-learning) - [Daniel Schildt](https://github.com/d2s/knowledge) - [Julian Shapiro](https://www.julian.com/) - [Gordon Brander](http://gordonbrander.com/pattern/) - [h0p3](https://philosopher.life/#h0p3) - [Karlicoss](https://beepb00p.xyz/exobrain/) - [Victoriano Izquierdo](https://www.notion.so/Learning-81054755c60d4d628e3f1cc7a95e4e7f) - [Piotr Stojanow](https://wiki.stojanow.com/) - [Sergio Gasquez](https://sergiogasquez.notion.site/sergiogasquez/Sergio-Gasquez-Personal-Wiki-0d2f9be521094316aa12fcbbc5d20fab) - [Paul Copplestone](https://paul.copplest.one/knowledge/) - [Hiran Venugopalan](https://hiran.in/notes) - [Liz Code](https://lyz-code.github.io/blue-book/) - [Simon Späti](https://brain.sspaeti.com/) - [Jonathan Porter](https://eatsleepdata.com/) - [Jacky Zhao](https://jzhao.xyz/) - [Pelayo Arbués](https://pelayoarbues.github.io/) - [Tom Critchlow](https://tomcritchlow.com/wiki/) - [Mario López](https://brain.drmario.tech/) - [Alex Turner](https://turntrout.com/) ## Compilations - [Meta Knowledge GitHub repository](https://github.com/RichardLitt/meta-knowledge) - [Second Brain Collection](https://github.com/KasperZutterman/Second-Brain). - [Best Of Digital Gardens](https://github.com/lyz-code/best-of-digital-gardens)
