Dear Flexible System Designers,
and especially all the Flexible Visual Systems owners, I finally took the time to make a page where I collected all the sources I used for writing my book. It was fun going through them again, and I was surprised how many of them are now available as free downloadable PDFs.
Let me know if I am missing any great links:

Have a great week!
