How Many Documents in a Gigabyte? Our Latest Analysis Shows A Shifting Pattern

Catalyst_How_Many_Docs_2017Since 2011, I have been sampling our document repository and reporting about file sizes in my “How Many Docs in a Gigabyte” series of posts here. I started writing about the subject because we were seeing a large discrepancy between the number of files per gigabyte we stored and the number considered to be standard by our industry colleagues. Indeed, in 2011, I reported that we were finding far fewer documents per GB (2,500) than was generally thought to be the industry norm, which ranged from 5,000 to 15,000. Continue reading

By | This entry was posted in Insight Enterprise and tagged on by .

Catalyst_Insight_Enterprise_Series_Wrap_UpWe hear regularly from our corporate clients of their desire to get a better handle on e-discovery costs.

Tackling the Tower of Babel of Multi-Language Corporate Discovery

Do you know where in the world your company’s next legal matter will arise?


The possibilities are more far-reaching and less predictable than ever before, as businesses expand their operations and markets throughout the globe. Amid a complex international legal and regulatory environment,  businesses can face lawsuits in any number of forums and are subject to investigations by any number of government entities.

How to Better and Safely Integrate Legal Holds, Collection and Review in E-Discovery

Catalyst_Safely_Integrate_Legal_HoldsDid you know that messing up a litigation hold can get you criminally indicted?

It happened to Volkswagen AG. Its mishandling of a legal hold resulted in the federal indictment of six current and former employees on charges of perjury and obstruction of justice. And to add insult to injury, an in-house lawyer was named an unindicted co-conspirator. On Jan. 11, 2017, VW agreed to plead guilty to the charges and to pay a $2.8 billion penalty. Continue reading

In this research we answer two main questions: (1) What is the efficiency of a TAR 2.0 family-level document review versus a TAR 2.0 individual document review, and (2) How useful is expert-only (aka TAR 1.0 with expert) training, relative to TAR 2.0’s ability to conflate training and review using non-expert judgments [2]?

Robots Taking Our Jobs? In E-Discovery, AI Doesn’t Replace Lawyers’ Work, It Enhances It

Catalyst_Robots_Taking_Our_JobsWe’ve all heard the threat: Robots powered by artificial intelligence soon will replace attorneys in e-discovery. That was even the suggestion of the 2011 headline in The New York Times, Armies of Expensive Lawyers, Replaced by Cheaper Software.

Not surprisingly, the actual Times article was less alarmist than the headline, making the point that AI and machine-learning tools can be used to lighten the load on lawyers, but not to take it away altogether. Continue reading
