Being a wall, my diet is composed almost entirely of post-its, though I do also enjoy the scents of food wafting through the library, and potatoes are a favorite in that department. Many of my human assistants enjoy potatoes. One has a partner who claims to have eaten potatoes prepared 52 different ways. The Potato in the Human Diet (O’Neill Library TX558.P8 W63 1987) says potatoes are grown in 132 of 167 independent countries. For the potato-obsessed, I must recommend reading Potato: a history of the propitious esculent. (O’Neill Library SB211 .P8 R43 2009).
