Pretty outdated but still worth a read if you are thinking of selling books online.

Helpful book but dated. Could have used more info on how to use social media to promote my bookstore. Excellent resource for where to find books to sell. Wanted to know more about building my own amazon web book store

Seriously dated but seems to have some good general advice and solid principles to follow if you are going to go into online bookselling.

A clear and thorough overview of online bookselling, covering all the steps from acquiring books to filing taxes on the profits. I would give it four stars if it were not out of date in many of the details. (For example, it lists half.com as one selling venue, but that went out of business in 2017.) It concentrates on Amazon sales, and much, but not all, of that is still relevant. More importantly, much of the general information about describing and pricing books, daily practices to keep the business running smoothly, and responding to customers is still good advice. The writing style is informal but clear. The book includes appendices including a glossary of book-related terms, common abbreviations, and references.
