[Dragaera] Copyright date for Cycle poem?

[Elizabeth Dalton]

I'm working on more shirts for the Adrilankha Gift Shop (shameless plug: 
http://cafepress.com/dragaera) and this batch of designs involves House 
animals and the signature lines from the Cycle poem. I can't find the 
copyright date for the poem, though. It appears in my omnibus _Book of 
Jhereg_, but I don't think it first appeared in Jhereg, did it? Since I 
have most of the titles in omnibus editions, I can't check this in my 
copies.

Thanks for any info,

Elizabeth
