From Paul Burston's blog:
"The Prize is for a first book which explores the queer experience and is open to any work of poetry, prose, fiction or non-fiction by a writer born or resident in the UK, published in English within the past twelve months.
Self-published works in both print and digital formats are eligible for submission.
Works must be submitted to The Polari First Book Prize by the publisher.
In the case of self-published works, works must be submitted with a one-page/A4 size letter of support describing why and how the project has been self-published.
The winner of the 2011 Polari First Book Prize was James Maker, for his memoir 'Autofellatio' (BIGFib), which began life as an e-book.
This year’s Prize is for books published between Feb 1, 2011 and Feb 1, 2012."
