As an avid reader, the author sought to find a system for organizing notes from books for easy reference later on. They explored various methods, including creating an index with abbreviations, using notecards and a commonplace book, visual note-taking, exporting highlights from e-readers, and storing notes in apps like Evernote. Each method has its benefits, such as annotating physical texts quickly and easily, waiting for a week to ruminate on ideas before copying them, and organizing notes with tags or notebooks. The author also discussed the importance of sharing book notes and highlights online, making it easy to share with others, and the potential to use apps like Zapier to automate tasks. Ultimately, setting up a system for organizing and cataloguing what you read allows you to reflect back on the information later and get the most out of your library.
