Many rabbis and educators have always had a book or two in them and have just not invested the time to sit down and crank it out.
Now is the time to do so – and the book can even help generate funds for you/your organization! We recommend that you consider publishing it using a print-on-demand (POD) service so the books are printed one at a time when needed. Consequently, there is no need for the significant lay out of thousands of dollars on your part.
The best/easiest print-on-demand service is KDP (formerly CreateSpace), owned by Amazon. Their quality is indistinguishable from a bookstore publication (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 Kindle at the same time. You can have a standard softcover book printed in B&W at KDP for around $4.
