Hello @jerrybanfield
This is an exhaustive list, I am bookmarking this post to read later, all the systems you listed were good.
Though some of them were made easier due to the influence you have gotten online. The one that I liked the most was that of selling your Mom's books on eBay.
I am an avid reader and my book collection is growing, i like the idea of making money from it in the future.
Thanks for sharing.
@ogochukwu thank you very much for reading and commenting about what you liked best! I am happy to hear you can now picture the book collection as growing in value!
