Hi Joshua,
For starters, there are always a lot of chapbook contests in the general poetry arena. A well sequenced haiku collection could stand a chance.
re:
THE UNWORN NECKLACE, Snapshot Press, 2007
Although Roberta Beary's para-
"verse novel" was published by Snapshot Press, if we can set that aside, as well as set aside that in 2008 it was named a Haiku Society of America Merit Book Award prize-winner...
What shows that a haiku collection can do well outside the haiku arena is that it was selected as a finalist in the Poetry Society of America’s William Carlos Williams Award, and the first book of haiku to receive such recognition.
I remember on, possibly the PSA blog, or Ron Silliman's blog I believe, that a couple or so 'haiku poets' attacked the book, and I did step in and calm things down. We must support each other!
Bill Higginson, the fine gentleman who gave us so much, had this wonderful thing to say, and we need to read it again:
Announcement:
Roberta Beary’s The Unworn Necklace Finalist for William Carlos Williams Award from Poetry Society of America! (22 April 2008 by wordfield)
https://haikaipub.wordpress.com/2008/04/22/announcement-roberta-bearys-the-unworn-necklace-finalist-for-william-carlos-williams-award-from-poetry-society-of-america/I'm shocked that I was the only haiku poet to LIKE this!
I regularly help, as Call of the Page, with haikai manuscripts, and look to the bigger picture.
Roberta's book? It started off as a softcover edition and continually sold out its reprints. That meant it was a calculated gamble to bring it out as a hardback, which sold out!
The softcover edition is into its 5th print run.
Why all this? Because things changed in the publishing world, and the poetry world (books and events etc...) many many years ago.
Even big publishing houses expect everybody, and I mean everybody, to promote their book and the publishing house with vigour and successful vigour!
I saw Roberta do this in spades, both for her book and the publisher, in fact she did a lot more than that. And she was indefatigable! I have a softcover and hardcover and music versions!

So it's been down to the author, for more than a decade across the publishing genres, to promote promote promote.
On a sad note those haiku speciality publishers outside the big haiku houses of Red Moon Press and Snapshot Press barely have any sales. Why is this, when there must be around 500 plus regular haiku poets on social media platforms?
And self-published? There is a long honorable history, even before Charles Dickens, of bringing out our own books.
Of course Dickens had to do it, and learnt from his friend HC Andersen who also very quickly brought out a winter classic to garner income.
A Christmas Carol:
http://davidabramsbooks.blogspot.com/2012/12/the-greatest-self-published-book-world.htmlI also know very well a best-selling author in the haikai world who is not justly recognised, possibly because she is a best-selling author! Her books are self-published.
The author is the 'engine' and a publishing house will only do so much, or so little.
So she isn't in "the cool kids crowd" or necessarily has "the money to publish their own books" and uses Amazon Print on Demand platforms.
My
Does Fish-God Know has never had a book review in the haiku print journals, and I think got a bit of a mention on one online journal, that's it. But I regularly told it's one of the best haiku collections around, and it was published way back in 2012!
Also, and sorry to say this, but this is another woman, so maybe this is a male thing? ;-)
ai li, quietly many years ago, and I think I was one of a few who noticed her come back, released high quality Kindle editions of her poetry (haiku, tanka, cherita). They were and are sublime, high production values (of course). And she has come back to the haikai world with a bang!
I was also the only one to step forward to help with two Snapshot Press launches. When there was a call out for help for the Wingbeats publication, I was the only one to step forward. I got the press a stall at the Royal Festival Hall, during the huge half a million attended Mayor's Festival in London. Karen and myself helped with the day's second launch as well! That was at the Poetry Society (UK) venue and cafe. There's a picture of myself and John Barlow, the last haiku poets standing, at around midnight in a bar-club around the corner. Then I organised a massive launch in the City of Bath. It was so successful I had to get the editors and guest poet upstairs for health and safety. And by the way, the independent bookshop did incredibly well on other sales that evening.
It's all hard-grafting, I was often on my knees, but kept going.
Now we can only do online anyway. The promotion side of things can be via blog tours, and online festivals, and haiku zoom meet ups etc...
So the book itself?It's about how the collection is put together. If we do just a generic competent collection we might get a few sales. If we push the boat out, just as Roberta, ai li, and the other author, the world is your oyster! But it is a lot of sheer grafting, meaning time, energy, enthusiasm, passion, and ways of getting the book out there, and not just in the obvious ways alone.
Lulu and Amazon mean you don't pay. Of course it's sensible to order at least one softcover book to check for layout errors etc... But that's cheap to do in cash, one single book, which before it's public, you can knock down to its lowest retail price. Then bump up the price when you go public!
We aren't women, but as men, we can try to be 'nearly' as good as them, fingers crossed!!!

warmest regards,
Alan
I the US, there seem to be two options to getting a physical haiku book published. One, of course, is Red Moon Press. The other seems to be self-publishing.
In the UK, there seem to be two or three option (Alba, Snapshot, etc.)
Obviously, we're a niche market within a niche market, but I'm wondering if anyone knows of any other presses that routinely publish haiku books. This just seems a limited option for folks who either aren't in the cool kids crowd or, alternately, don't have the money to publish their own books.
