I wrote 17 stories last year, ranging from just over 1000 words to just over 12,000, and totalling over 78k words. A good chunk of that, just under a third of it, was for Yuletide. Still, not a bad haul, for an otherwise fraught and busy year.
The fandom break-down is alphabetical, and within each fandom, by word-count:
Alexander Trilogy:
Foster-Child of Silence and Slow Time (1124 words) (Yuletide)
Autumn, Fall (1062 words)
Hadestown:
the night, the beloved body (12163 words) (Yuletide)
Harry Potter:
Tieresias Trap (8608 words) (w.i.p)
and the life (7709 words) (w.i.p)
The Wish to Move Backward (3166 words) (r-s games)
Mahabharata:
kounteya (6481 words) (w.i.p)
Maurice:
Isn't Love (1170 words) (edited and posted to AO3)
Night Watch:
not the squares of the cinema but envelopes of affection (1428 words) (Rare Women)
Penny Dreadful:
Between the Shadow and the Soul (5027 words) (Yuletide)
The Charioteer:
conditions best suited of all to unreserve (9789 words) (w.i.p)
The Thousandth Man (6569 words) (Yuletide)
Not a House or Even a Tent (6084 words)
restless nights in one-night cheap hotels (3514 words)
A Vote of Thanks to Mr. Abse and Lord Arran (2529 words) (Yuletide)
the unwearying heart over the waves of the sea (1500 words)
Auld Lang Syne (1001 words)
ETA: Because it's right there at the top anyway, my total stats on AO3, over 172 fics spread in 38 fandoms (not counting variations of the same fandom) are:
Woefully small, compared to most who have been around five years and change, but I'm not remotely prolific.
What's interesting about the stats is that I can practically chart my mental health by looking at them. 2014 has been a good year, at least since August and is certainly the most I've written in a year, with 2013 clocking in at just below 60k (59861 words) and 2010 a distant third (42817 words). 2009 gets off easy, since that's when I got into fandom and was writing almost entirely drabbles, and because a lot of what I was writing was in role-plays on various communities. You can see the worst of the depression just by looking at output-levels: in 2011 I wrote just over 16k in 10 stories, of which 7 were for Yuletide; in 2012 I wrote 21k or thereabouts, missing Yuletide entirely but getting invested in The Charioteer as a writing fandom.
My aim for 2015 is to write at least 80k of fanfic, and hopefully get a chunk of work done on the novel.
