Editorial policy

Who writes our content

Guides are written and edited by the UsedBook.com Editorial Team: people who buy, sell and collect used books, with input from booksellers and contributors we work with. We publish as a team so readers get one consistent standard.

Our standards

• Original work. Every guide is written for UsedBook.com. We do not copy, spin or machine-rewrite other sites’ articles.
• Accuracy over excitement. We avoid invented statistics and inflated value claims. When something varies by publisher, era or market, we say so.
• Practical first. Each guide should leave you able to do something: check an edition, choose a selling route, store a book properly.
• Sources. We rely on hands-on trade practice, established bookseller conventions and reputable references, and link to primary sources where useful.

Independence

Advertisers, sponsors, affiliate programmes and buyer partners have no say over our guides, tool logic or recommendations. Sponsored placements are labelled.

Updates and corrections

Each guide shows the date it was last reviewed. Marketplaces and policies change, so we revisit guides regularly. Spot an error? Tell us — we correct promptly and gratefully.

Tools

Our tools encode widely used trade rules of thumb. They run in your browser, explain their reasoning, and always state that they are estimates rather than appraisals.
