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. Update as of 2020: part of the election ephemera collection has been digitized and is now available in Berkeley's Digital Collections.
