The O’Brien Press is an established and respected publisher that is based in Ireland. They favour Irish voices, but are open to international submissions. They publish nonfiction for adults, and fiction and nonfiction for children.
If you are submitting to them from outside of Ireland, I would make sure to spend even more time with their catalogue and buy and read a book or two to make sure you are a good fit.
I cannot stress this enough, but please do not submit, particularly if you live outside of Ireland, unless you feel like your work is a particularly good fit. We have had a number of presses close to direct submissions because of mass submissions recently. Mass submissions rarely, if ever, result in your manuscript being accepted.
They are particularly looking for work from diverse backgrounds (BAME, LGBTQ+, authors with disabilities, etc.) and New Irish voices.
They have good distribution within Ireland and internationally. They are usually only open to postal submissions but at the time of writing this, because of COVID-19 they are only accepting submissions via email.
They usually respond within 8-10 weeks but under current circumstances these goals are less likely to be met. They ask submitters to be patient.
They ask that you send a cover letter, synopsis, and full manuscript via email. To learn more please visit their website here.
