IUPAC (the International Union of Pure and Applied Chemistry) has published a new chemistry reference work, the IUPAC FAIR Chemistry Cookbook. It was written by multiple experts in chemical information, and is freely available through IUPAC. This online book explains how to share and reuse chemical data, and you can read more about it in this brief article.
A link to the Cookbook is here: https://iupac.github.io/WFChemCookbook/intro.html
