Amazon's 1,082-volume Classics Collection: $7,989
Carl Bialik from the WSJ writes "Who would buy 828 feet worth of books, for nearly $8,000, that would take 20 years to read at the rate of one title per week? And how much does it cost to ship? The Real Time columnists at the Wall Street Journal Online ponder these and other deep questions raised by Amazon's The Penguin Classics Library Complete Collection, whose sheer jaw-dropping enormity reminds them of e-tailers' wacky offers during the dot-com boom. 'We think the collection is a perfect fit for more than a few software engineers we've known -- smart, self-directed people who are eternally curious, yet abhor wasting time intellectually and can't hide their impatience with the fuzziness of liberal arts,' Jason Fry and Tim Hanrahan write. 'For them, here's a pre-selected, pretty comprehensive list of Western classics, assembled for purchase with a single mouse-click -- and available in a form that eschews frills for portability and ease of use. Think of it as Humanities In a Box. OK, a Very Big Box.'"
I am an ex sotware engineer in my fifties who did exactly this. In my 20's I collected about 2000 core classics so they could always be at hand. I've read most of them too.
I can't say whether they have "improved my life" since the substrate of my perspective now depends upon them. For example, because of them I decided that engineering is too limiting.
But if you have faith that generating interconnections in the brain between sense, experience and imaginitive possibilities is a good thing, then this is the way to go.
