Practical AI: A Field Guide to Working with Claude

One field guide, built for the classroom in three matched editions. Each chapter pairs plain explanation with hands-on practice and review questions, organized around a single lens that outlasts any one tool: judgment over features, and the human kept firmly in the loop. The technology will keep changing. The thinking is what lasts.

Author · Field IT Engineer · Founder, Lexington Road Press

M. Emmett Townsend is a Field IT Engineer with hands-on experience deploying and maintaining technology systems across many locations — the kind of work that happens in the real world, not in a lab.

He came to AI not as a theorist but as a practitioner who watched the right tools, used with judgment, change what was possible for ordinary people. He built the Practical AI classroom line to put that same judgment in a student's hands — plain language, real practice on the page, and a habit of questioning the tool rather than trusting it blindly. The technology will keep changing; the thinking is what he wanted to teach.

April 19, 1775

A name carried down the line.

Lexington Road Press takes its name from the road where America began to fight for itself — and from a family that was there when it happened.

On the morning of April 19, 1775, along the road between Lexington and Concord, Daniel Townsend gave his life covering the escape of his kinsman Thomas Townsend — the direct ancestor of the press's founder. One man stood so another could go on. The line continued because of it.

"Every book we publish is meant to do the same small, stubborn thing: help someone get safely down the road ahead."

That is the spirit of this imprint — built on the belief that good work, done thoughtfully, should serve people. We publish books that meet readers where they are and help them move forward with confidence.
