A key question for trial lawyers is when web content appeared online. Gaps in organizational recordkeeping, turnover in digital systems, and reliance on cloud services make historical web content particularly susceptible to loss. Web archives such as the Internet Archive Wayback Machine (IAWM) as well as other available free tools make it possible for litigators to ascertain when web content was published and how it has changed over time. In this session, we will review the capabilities and limitations of IAWM with evidentiary use in mind and share other techniques for performing web archaeology.
