ballot box with California flag in background

These guides contain concise descriptions of ballot measures including non-partisan analyses, official voter information, background materials, pro-and-con websites, newspaper articles and editorials, opinion polls, political endorsements, and financial contribution records. (From 2010-16, the guides were published simultaneously online at californiachoices.org.) 

The library also maintains an extensive collection of print clippings and election ephemera, dating back several decades. Check OskiCat or email igsl [at] berkeley.edu for more information. We have begun digitizing the ephemera collection, and some parts are now available in UC Berkeley's Digital Collections.
