Dewey: The Small-Town Library Cat Who Touched the World by Vicki Myron,

Dewey (aka Dewey Readmore Books) has a horrible start to life - he is shoved through the after-hours book-return slot at the public library in Spencer, Iowa, on one of the coldest nights of the year. Amazingly the little ginger ball of fluff survives the night and is discovered the next morning by Vicki Myron, head librarian. Vicki relates his story, intermingled with her own, from this point until his death 18 years later in 2006. Vicki formed a bond with him, as Dewey was not the only one who had endured hardship - Vicki was a single mother who had lost the family farm and survived an drunken, neglectful husband. The people of Spencer were going through tough times due to the farm crisis of that time; depression, both literal and mental, seemed to be everywhere.

Dewey's unconditional love of people, fun and rubber bands gives a new lease of life to the local people of Spencer after he is adopted as the Public Library cat, then the interest spreads outwards around the world. Visitors found it hard to be sad when Dewey wrapped himself around their legs - jumped in their laps for a sleep - and played hide and seek.
A nice, sweet story about a very special cat.

I would have liked a little more about Dewey and a little less of the author's life story and a little less of the history of the town.
