This pocket guide is designed to help federal judges manage the discovery of electronically stored information (ESI). It encourages judges to actively manage those cases involving ESI, raising points for consideration by the parties rather than awaiting the parties' identification and argument of the matters. The guide covers issues unique to the discovery of ESI, including its scope, the allocation of costs, the form of production, the waiver of privilege and work-product protection, and the preservation of data and spoliation. As you are reading, you may encounter some unfamiliar terms. Many of these terms are defined in a glossary at the end of the guide.
