So, I've tracked down and bought quite a few soccer and history books with the Kickstarter funds. Here is a sample:

Inverting the Pyramid by Jonathan Wilson

The Ball is Round by David Goldblatt

Morbo by Phil Ball

Barca: A People's Passion by Jimmy Burns

La Roja by Jimmy Burns

Soccer Against the Enemy by Simon Kuper

Mardid-Barca: Historia de un Desamor by Julian Garcia Candau

50 Teams That Mattered by David Hartrick

The Battle for Spain; The Spanish Civil War 1936-1939 by Anthony Beevor

Gracias, Vieja by Alfredo Di Stefano

The Splintering of Spain by Chris Ealham and Michael Richards

La República Española y la Guerra Civil by Gabriel Jackson

Todos los Jefes de la Casa Blanca by Juan Carlos Pasamontes.

The Franco Regime 1936-1975 by Stanley Payne.

Historia del F.C. Barcelona: El Barca, un club, una ciutat, un pais by Jaume Sobreques.

I already owned "White Storm" by Phil Ball. I'm definitely going to check out lots of other books, but I need cash to pay the editors, artist, conversion costs, copy right claims, and, of course, the super neat prints for several Kickstarter backers. Thus, to the library!
