I’m a big fan of self-publishing, especially for poetry. Alan Finder in the New York Times has some useful guidance on this. From the article:

Digital publishing and print on demand have significantly reduced the cost of producing a book. The phenomenal growth of e-readers and tablets has vastly expanded the market for e-books, which can be self-published at little or no cost. Writers who self-publish are more likely to be able to control the rights to their books, set their books’ sale price and keep a larger proportion of the sales.

But one thing has not changed: most self-published books sell fewer than 100 or 150 copies, many authors and self-publishing company executives say. There are breakout successes, to be sure, and some writers can make money simply by selling their e-books at low prices. Some self-published books attract so much attention that a traditional publishing house eventually picks them up.

I highly recommend reading the article.
