Since I enjoyed 'In Short' so much I just got two follow-up books
In Brief -
http://www.amazon.com/gp/product/039...ls_o02_s00_i00
and
Short Takes -
http://www.amazon.com/gp/product/039...ls_o02_s00_i01
Both focused on short creative non-fiction (In Brief is focused more on the personal/memoir style)
