Two hardcover reference books, two very different eras, and one decision to make. On one side is the TIME Your Brain: A User's Guide, a magazine-style hardcover from TIME editors listed at $6.98. On the other is the Giant Handbook of Computer Projects by The Editors of 73 Magazine, a 1979 hardcover listed at $25.00. Both come from editorial teams, but they point in opposite directions: one explains how the human brain works; the other collects hands-on computer projects from the dawn of the home-computing hobby. The real question isn't whether these are good books - it's which one earns a place on your reference shelf.
Quick verdict
If you want a readable brain-science overview at the lower listed price, the TIME Your Brain guide is the clear pick. If you want a time-capsule computing handbook from 1979, the Giant Handbook of Computer Projects is the more distinctive find. Choose by purpose: modern science reading versus vintage computing history.

Product notes
TIME Your Brain: A User's Guide

This hardcover, ISBN 9781603200943, lists Jeffrey Kluger and the TIME Magazine Editors as authors. Its listed condition is Good, which makes it the stronger-condition option in this comparison. The subject - your brain, framed as a user's guide - suits readers who like accessible science writing in short sessions. Because it's a guide rather than a project manual, you won't find circuit diagrams or step-by-step builds; that's the limit if you came expecting hands-on projects. For a general reader, it's an approachable hardcover with a solid listed condition.
Giant Handbook of Computer Projects

This 1979 hardcover carries ISBN 9780830697243 and comes from the editors of 73 Magazine. The listing notes Acceptable condition, a coffee spot on the bottom, and a mark running to page 24, with no writing or highlighting. What you're paying for is era: a project handbook from 1979 captures the early home-computing moment in a way a modern book can't. The trade-off is the documented wear - Acceptable is a step below the TIME guide's Good condition. If you collect computing literature or want a period-correct reference, this one delivers historical texture, as long as you accept the condition.
Final choice by use case
Pick the TIME Your Brain: A User's Guide if you want a modern science read in a hardcover guide. Pick the Giant Handbook of Computer Projects if you want a 1979 computing reference with project plans. Both books can earn a place on a reference shelf; the best fit depends on whether you're buying for the subject or for the era.
