This document discusses open notebook science, which aims to make the scientific process more transparent and collaborative. It describes how open notebook science makes raw data, calculations, assumptions and revision histories publicly available. This allows other scientists to reproduce and build on the reported results. The document also addresses challenges around archiving and preserving open science data and notebooks so they remain accessible over the long term. It outlines current archiving solutions used by the open notebook science community such as daily backups of crucial data and semi-automated snapshots of the entire scientific record.
