Hey, Ian, I see you're up for a nomination in the BSFA's novel catagory (Plus an impressive turnout for Newcon in the shorts). Best o' luck, chap!
Er, anyone can be nominated. You just need a member of BSFA to nominate one of your stories or novels. One of mine has even been nominated.
I think they just choose the five novels, stories, etc. with the most nominations for the shortlist. Then everyone votes on that - members of the BSFA and members of the Eastercon. The awards are presented at the Eastercon.
Last year, due to delays in obtaining the rights to some pieces and printing issues, the booklets actually arrived a few days after the voting closed... but such is life.
