Shameless plug for mine and my wife's project, http://www.visualhaggard.org. We have extremely high quality scans of illustrations from many editions of H. Rider Haggard's work. Thanks for your time!
I commented elsewhere on this thread about reproductions: https://news.ycombinator.com/threads?id=cpach
Just out of curiosity, have you considered making print reproductions?
You know, we hadn't considered making prints but I've always wanted to merchandise. The goal was to make an academic resource and to collect and preserve the images in large resolutions.
