Books printed-on-demand
I produce one or two books per year. I use a print-on-demand (POD) service so the books are printed one at a time when needed. The best/easiest print-on-demand is KDP (formerly CreateSpace), owned by Amazon. Their quality is indistinguishable from a bookstore book (in fact many books from NY publishers are printed POD), and they have the added virtue that you can sell the books on Amazon, and it integrates with making digital books for the Kindle at the same time. I can have a standard softcover book printed in B&W at KDP for around $4. Small run books make ideal gifts. — KK
