Add up all the digital memory (in cell phones, computers, and other devices) and analog media (for instance, paper) and it goes to a very big number. The authors try to put it in perspective, which for me brought home how insignificant my line of work can be. (All of our information is still less than 1% of what is encoded in the human DNA?)

On Tuesday, the Poynter Institute (a school for journalists, future journalists, and teachers of journalists) released results of their — an examination of reader behavior in the print and online mediums. An article on their website goes into more detail about the initial data but what caught my eye as of interest to the library community is the headline (“The Myth of Short Attention Spans”) and this conclusion “The reading-deep phenomenon [thoroughly reading a selected story] is even stronger online than in print.” Their website site has .
