Public Libraries?

[Lil Reads]

You might have better luck promoting your books at a branch you have ties to; some libraries have a local authors collection and will buy copies of books from authors who live near the library or in the county.

I would try to have as many meet and greets as possible with people that follow you already. Although it's old fashioned in our social media driven world sometimes word of mouth is the key.

Libraries have buyers just like any other business. They decide what to put on the shelves. It's possible to pitch to them just like agents, but success is going to be more difficult for an indie author than a big pub house.

My local library is under threat of closure, but they welcome efforts to promote and fundraise. As another poster suggested, you could run some free (or low cost) writing classes and promote your book to participants.
