A new report from Pew Research Center, "Journalism Partnerships, A New Era of Interest," provides short case studies of five efforts by local news organizations to collaborate with other news organizations.

As traditional news organizations tighten their belts and emerging news start ups embrace lean operations, pooling resources is becoming more appealing even among former competitors.

The report looks at cases where news organizations joined forces to co-produce or share news coverage, where a small start up gained exposure by sharing stories with a larger traditional news partner, as well as two partnerships that helped local public broadcast outlets develop local news muscle.
