A timely manual for advocates and policymakers was published before the 2007 elections. The book Electoral Reform in the Philippines: Issues and Challenges, written by Prof. Clarita Carlos in partnership with KAS and the Center of Asia Pacific Studies, proposes two alternative omnibus codes. The book analyses electoral reforms in both presidential and parliamentary systems. This comprehensive reform manual include recommendations on computerization, voters registration, advertising, pre-election surveys, campaign finance, and appreciation of the ballot and party list systems.
