I’ve started making blank books from recycled paper I find around work and home. The paper is blank on one side, so it provided plenty of space for notes and doodles, and even provides inspiration based on the printed matter on every other page. They tell a story about where they were created, as you can imagine an art school computer lab recycling bin would yield much different printed material than that of an accountant. Other interesting discussions that have come up about these books are that of privacy (including printed matter with sensitive personal data) and chronology (writing over the past with the present).
