My books in libraries
Yes it’s possible, apparently, to indie-pub a romance book and see it acquired by libraries. If you use Smashwords (and opt into Overdrive for digital books), Findaway Voices (for audio books), and CreateSpace (now Amazon print, for print books) then the library option is just there already.
I didn’t think about it all that much because I’m not used to the public library system the way other countries know and use it. I associate libraries with schools, a preference for educational material, and if someone representing a library does tell me they want romance titles I assume their budget will be very limited. The few times I’ve worked with libraries with budgets it wasn’t easy, because of the paperwork involved. (Which has led to: if my books are in a Philippine library, they’re through my local publishers, or I’ve donated the books.)
Then it occurred to me to check if opting into library distribution has led to…my books being in libraries. And yes they are! This usually starts with a library patron making a request, and the book being acquired. Look into this if you can.
These are my books in different libraries. Putting up links to my two most recent releases first, entries found as of December 2018. Thank you for requesting, acquiring, and reading a book by a Filipino author!
