Nowadays, there are a variety of very quick, reliable, and cost-effective ways to self-publish a book online. Sites like Lulu made it very easy to create a sefer for under $20. However, they don't provide an easy stream in the Judaica and Seforim stores around the world (and the USA in particular).
Are there any effective ways to get a self-published sefer into all of the Seforim stores, or at least carried by a few distributors? Looking for any direction or experience.
