Amazon also offers philatelic books for free in digital format. These are classic texts which may not be the latest as far as publication dates go, but there is useful information in these pages and one cannot argue with the cost. They are well worth the time to download and review to ensure you have all the information available from the greatest number of sources in your interest area. In part 4, we’ll list titles not included in earlier posts.

I also found “The Orange Penny Mystery” on Amazon, a mystery novel involving postage. I haven’t read it yet though… It’s on my list.
Tony, Thanks for the additional book, that’s one I’d not found! That’s a good idea and one I’ll address in part 6. Part 4 is for other books at Amazon I’ve found and part 5 is for ebooks from other places than Amazon. Please continue to read and comment, your help is appreciated I’m sure by all our readers.
