Using the MemexJUL 14 2003
I've been reading a lot over the past few months, both online and in book form. Not unusual, but I've noticed that I retain a lot more from my online reading than from the offline. My recall of names, facts, circumstances, themes, and lessons from articles I've read online is excellent, but not so good when it comes to books. Part of it is that I approach book reading as a leisure activity and not as work or study, although I'm not sure the opposite is necessarily true for Web reading (partially perhaps, because I do use the web to brush up on design and programming issues -- work stuff). But the bigger reason for the difference is probably due to the nature of what the task of reading entails in those two media.
Books are self-contained. There are 332 pages in my copy of The Selfish Gene (incl. endnotes). There might be a bibliography, but unless you're in the library, reading up on any of the 200 or so references contained therein would prove challenging. Everything you get with a book is in between its front and back covers.**
With the web, you're always in the library. It's not always a proper library (some of the "reference" materials can be a little sketchy), but it's better than nothing. And the materials you want are very often hyperlinked right in the material you're reading for instant research gratification. Web reading is a deeper and more active type of reading. I can completely research a particularly interesting topic, jumping from site to site to Google to site and back to Google, hunting down exactly what my brain is jonsing for, and skim over the stuff I'm not so keen on. I'm not dependent on the author of the book to give me exactly what I want; I can "write" my own book of sorts, editing the subject matter as I see fit. It's this active reading -- researching really -- that I think is responsible for the much higher rate of retention with online reading.
** "Ha ha, not quite!" you're rightly saying to yourself. You've got your whole lifetime of experience and a healthy imagination to draw upon. Two covers my ass, books are as full as you want to make them. That's one of the drawbacks of reading on the web for me. My recall is excellent, but I typically don't stop to ponder like I do with books. There's always that next thing to click on or research. I don't have to work out for myself on which points Dawkins disagrees with Stephen J. Gould...I can just go and read for myself. I might recall more from web reading, but I think I get more from books. (Although, online research while reading a book is a very potent combination...if you remember to ponder before scurrying off to the web for easy answers.)

I very often find the same thing true with me. When I sit to read on the computer, I'm going on a mission to gain knowledge whereas if I just open a book or magazine, it is to take up time.
Oh, and that "The internet is shit" thing... well, that's dumb. Both are useful for many different uses.
