I recently got two books on our favorite multicolored plastic subject: A Million Little Bricks by Sarah Herman, and The Brick Bible by Brendan Powell Smith.
Let me preface by saying that both books are beautiful. High-quality glossy paper and quality color prints. Don't get the kindle version, kids. Feel the heft of those dead trees in your hands. Mmmm. Delicious.
A Million Little Bricks is, unlike The Cult of LEGO (also great), a history of the company and the toy—NOT the fan community (although a short 10-page section does mention it, various conventions, and fan projects like BrickJournal). Any readers who can identify sets based on part number will geek out, and anyone interested in knowing detailed stories behind the progression of various LEGO themes, marketing to girls, and a more textured description of the company history and leadership will have a happy read. It's dense reading, but, well, what else are you going to read anyway? This blog?
And the dedication of the book is the cutest: "For Ian—because you love me enough to let me build your Unitron Monorail set 6991)". Collective awwwwww.
