I've just uploaded a beta of boo2pdf, an IBM BookManager to PDF conversion app & web service. I'm currently experimenting with the HTML to PDF backends and would like feedback with book files I haven't tried. Once the code is cleaned up, I will dump it on my site.
I have a large collection of old IBM machines and documentation. I want this documentation indexed by my own search facilities and Google for easy retrieval. PDF is widely read, while BookManager requires proprietary software and no search engines I know of parse it. This will probably be useful to Mainframers as well.
Take the web service for a spin here: http://ps-2.kev009.com/boo2pdf/.
