Reference for monoidal bicategory of spans?

[Mike Stay]

Can anyone provide a reference for the fact that given a category C
with pullbacks and finite products, you get a monoidal bicategory
Span(C)?

Hi Mike,

how about

Stephen Lack, R.F.C Walters, R.J. Wood, Bicategories of Spans as
cartesian bicategories, submitted to Theory and Applications of
Categories. (available from http://arxiv.org/abs/0910.2996)
