This book chronicles snarky rich kid (he is actually 35) A.J. Jacob's quest to read The Encyclopedia Brittanica from A-Z, in an attempt to become "the smartest person in the world". Jacobs breaks the book into alphabetical chapters and free-associates on the entries that he finds interesting. This book was by no means dull, but it was interesting in the way that flipping through the encyclopedia or the dictionary yourself is interesting-- as you scan the pages you find weird little tidbits that ...more

This was a little more like actually reading the Encyclopedia Britannica than I was really prepared for. I think it took me longer to read this book than it took Jacobs to read the entire Encyclopedia Britannica, too. So, I’m not sure what that says about my reading stamina. It took Jacobs something like a year to read the encyclopedia? I think it took me two years to read this book. Although I don’t really get how it’s possible that it took him a year because I feel like way more than half of t ...more

I saw this dude in person talking about his newer book ("The Year of Living Bibically"): he seemed quirky, intelligent, curious, funny, and overall quite interesting. In time I saw that he used the same one-liners in every medium available and he was kind of obnoxious, but this was before that. He cast quite a spell on me and I knew I wanted to buy one of his books then. He had just talked about "The Year", it was newer, and honestly it just seemed a lot more interesting than a book about readin ...more

What a thoroughly enjoyable book!

When Esquire editor A.J. Jacobs sets out to read the entire Encyclopedia Britannica, you can guess you're going to get lots of interesting trivia tidbits from the world's leading compendium of knowledge.

But what makes the book far more rewarding is that A.J. Jacobs is flat out funny. And after suffering through all the authors who attempt to write humor and do it badly, it is so good to be able to say that. I found myself laughing out loud every couple of pages.

This is the first book by the author who wrote The Year of Living Biblically, which I read last month. In this one, Jacobs decides to become the smartest person in the world by reading the Encyclopedia Brittanica from beginning to end. Jacobs has a separate chapter for every letter, and within the chapter he divides the sections out by subjects within that letter - highlighting important facts for us, and throwing in stories about how this quest is affecting his personal life - mostly making him ...more

I've read this book three times. Jacobs is funny and fantastic. Read anything of his.

An annoying book about reading the entire Encyclopedia Britannica that I was compelled to finish. Humour is subjective and I found Jacobs' nebbish, hypochondriac, regular Jewish guy persona to be pretty fake and forced (as well as pretty old, Woody Allen did it much better). (He's an Esquire editor, roomed with a Kennedy in college, goes on fab vacations, all while trying to portray himself as a bumbling oaf. If he had just fessed up to being an elitist with some intellectual pretensions I would ...more

I decided to clear my rating. I didn't find it particularly amusing, but it didn't repulse me or anything. The thing is, a lot of us bookish kids back in days of yore did find ourselves at some point sitting down and reading encyclopedias. So, as far as I'm concerned, Jacobs is way late to the game.

Definitely food for you brain, but upon purchasing this book I wasn't aware the chapters of the book went from "A-Z" each chapter containing his favorite words/definitions, mixed in with narrative of his life. I liked the author, but sometimes he could really get on my nerves..if i heard one more mention of visiting his parents in "East Hampton" and countless mentions of being an "upper middle class New Yorker" writing on his "white Macintosh lap book", or his complaining about how he couldn't g ...more

I could have done without reading this book. I thought it was cleverly compiled, but realistically, who wants to read a book with a listing of definitions? The only parts that made me want to keep reading were AJ's adventure on Millionaire and his journey to having a child. A novel concept, but not worth the 300+ pages of reading.

A.J. Jacobs has noticed an ever widening gap left from graduating from an Ivy League education. His solution, to read the entire Encyclopaedia Britannica, from A to Z. Follow A.J. as he works his way through all 32 volumes, that’s 33 thousand pages and 44 million words. His wife thinks it’s a waste of time, his friends believe he has lost his mind, but follow this unconventional task in this memoir.

As anyone who knows me can attest, I generally spout information to anyone who will listen to me. Most conversations begin: I heard on NPR the other day . . . For example, did you know there's a marsupial species in Australia whose male population only lives 11 months, the last month of which is spent obsessed with procreating or that a cockroach can live up to ten days without a head? Just one of the many useless bits of knowledge I have tucked away. AJ Jacobs wrote "The Know-It-All" as a quest ...more

What started out as a clever and funny tale of an epic chore -- reading the entirety of the Encyclopedia Britannica in one year -- quickly devolved into a study of one of the most annoying people I can imagine.

I read Jacobs' The Year of Living Biblically: One Man's Humble Quest to Follow the Bible As Literally As Possible last year and found it fairly enjoyable. Enjoyable enough to pick up his first book. Jacob came across as slightly neurotic but basically curious and endearing in Living Biblic

Author A. J. Jacobs' informative and hilarious romp through the Encyclopedia Britannica. Quite the page-tuner (unlike the complete Encyclopedia Britannica, I'm guessing).

Overall this is a book worth reading for both the knowledge and the humor. It was, however, at times rough going and I felt as if I was experiencing Jacob's challenge of reading through the encyclopedia but on an obviously much smaller scale. I think it was just too much material, as there is chapter for each letter of the alphabet and, though there are enough fascinating bits of knowledge scattered throughout with the occasional laugh-out-loud Jacobian moments, they seemed for a long stretch to ...more

I can no longer force myself to read this. I started reading it in August and have only gotten 46% of the way through. It clearly isn't happening, and there is absolutely no reason to continue. I'm really disappointed, because out of all of his books, this is the one that appealed to me the most. Also, I read The Year of Living Biblically by him and really enjoyed it. The problem with this is that it really does read like a condensed version of the Britannica. I expected it to be more interestin ...more

I picked up “The Know-it-All” immediately after finishing Jacobs’ more recent book, “The Year of Living Biblically”. I really enjoyed “Biblically”, and figured what worked for the bible would work for the encyclopedia as well.

In “The Know-it-All”, Jacobs aspires (tongue-in-cheek) to become the smartest person in the world by reading every word in the Encyclopedia Britannica. Jacobs does a great job mixing quirky/interesting/funny stories retold from the encyclopedia with stories from his life du

(Reread in October 2015, because I wanted to. Review below is from my first read of the book.)

Words cannot properly express how much I enjoyed reading this book. I read it not too long after reading Jacobs's A Year of Living Biblically, and I loved his writing style in both books. He's got a wonderful sense of humour, nicely balancing self-deprecation and personal anecdotes in a way that really allows you to get inside his head.

This book is written in sections much like encyclopediae, with the t

I purchased this book as a birthday present for my husband. I mean, look at the title... It has his name on it! (Sorry hon, you know I mean well.) While reading the book my husband would share with me funny little tid-bits and upon completion, told me he thought I'd really enjoy it... Why? Because I'm a 'Know it All' too? No, that can't possibly be true!

Anyway, this book is Great Fun! I know it sounds like the story of a guy recounting his foray into reading the entire library of Encyclopedia Br

I picked this up in the airport the other day and devoured it on a flight to California. What a great book! While I've never even thought of reading the Encyclopaedia Britannica from A to Z (or even one volume), as profound trivia fanatic I can totally identify with A.J. Jacobs' quest to make himself smarter. This book is part trivia lover's dream, part philosophical musing on one's insecurities as you get older and wonder about your place in the world. Jacobs is a terrifically self-deprecating ...more

This was awesome! Kind of like a hilarious, abbreviated version of a set of encyclopedias!

It's found under humor, but is sort of a memoir? The guy complains his brain is turning to mush because the only information he takes in lately is regarding pop-culture. Why can he name all the members of N'Sync, yet forgets major historical events? So he sets out on a quest for knowledge and commits to reading the entire Encyclopedia Britannica.

This book includes author-deemed high-points of the encycloped

I expected more. I was one of those weird kids who actually read two different encyclopedias . Read one the summer after 5th grade and another in 7th grade. The 1st was the world book and I continued to read the update volumes until I went away to college.

I expected less personal anecdotes and more interesting knowledge.

A stimulating, fascinating read. This book will, in the least, teach you a thing or two. What makes it such a good read is the authors sense of humor and how he creates a story around this seemingly nonsensical quest to read the encyclopedia. Each chapter filled with useless facts, fun life applications and a good laugh or two. I thoroughly loved this book.

A.J. Jacobs had me laughing out loud again. I love his awkwardness, his vulnerability and his ease at being able to constantly make fun of himself. I enjoyed his, " The Year of Living Biblically," a bit better because I found the subject matter more interesting. But, this is still such a fun book.

The author sets out to become the smartest man in the world with the help of the Encyclopedia Britannica. Yes, he read the entire encyclopedia from A to Z. Quite a reading challenge: 33,000 pages filled with 44 million words. Not as impressive as my reading of Mary Poppins from A to Z.

There is an additional argument for the choice of his subject for the book. It is A.J. Jacob’s one-way competition with his dad. His fat
