Announcing the Third Edition: Generative AI for Smart Legal Professionals

An Introduction to Large Language Models

We are pleased to announce the publication of the Third Edition of “Generative AI for Smart Legal Professionals,” authored by Merlin Search Technologies’ CEO John Tredennick and Chief Data Scientist Dr. William Webber. Originally published in the MIT Computational Law Report as “An Introduction to Large Language Models for Ediscovery Professionals,” this comprehensive guide has been extensively updated and expanded. The new edition officially debuted at EDRM’s widely attended webinar “Using Generative AI to Reengineer Investigation and Discovery Workflow.”

What's New in the Third Edition

This edition showcases Gen III, Merlin’s breakthrough integrated system that combines Find, Analyze, and Report capabilities into a seamless workflow for handling large document collections. Through practical examples and real-world applications, readers will see how Gen III transforms traditional discovery processes, making them faster, more accurate, and more cost-effective.

The Third Edition also features substantially expanded coverage of critical professional issues, including:

      • In-depth analysis of security considerations and privacy safeguards
      • Comprehensive guidance on ethical AI use in legal practice
      • Detailed examination of professional responsibility obligations
      • Latest developments in AI-related legal cases and regulatory guidance

From MIT to EDRM: A Trusted Resource

The book’s journey from its initial publication in the MIT Computational Law Report to its formal release at EDRM’s recent webinar underscores its significance in the legal technology landscape. EDRM, as the leading international standards organization for eDiscovery and information governance, provided the perfect platform for introducing this updated edition to the legal community. The accompanying webinar, which featured distinguished discovery professionals from Robert Bosch, HKA Global, Siera Data (Australia), and the former head of Global Discovery for Squire Patton Boggs, highlighted the pressing need for practical guidance in implementing GenAI solutions.
