We create economic value out of information when we figure out an effective strategy that includes aggregating, filtering and connecting.

"Algorithms choose which students sit together. Algorithms measure what the children know and how well they know it. They choose what problems the children should work on and provide teachers with the next lesson to teach. This combination of human capital and technology is called "blended learning."

So, the real question is, how do we design filters that let us find our way through this particular abundance of information? And, you know, my answer to that question has been: the only group that can catalog everything is everybody. One of the reasons you see this enormous move towards social filters, as with Digg, as with del.icio.us, as with Google Reader, in a way, is simply that the scale of the problem has exceeded what professional catalogers can do. But, you know, you never hear twenty-year-olds talking about information overload because they understand the filters they’re given. You only hear, you know, forty- and fifty-year-olds taking about it, sixty-year-olds talking about because we grew up in the world of card catalogs and TV Guide. And now, all the filters we’re used to are broken and we’d like to blame it on the environment instead of admitting that we’re just, you know, we just don’t understand what’s going on.

However, even experts can’t deal with all of the information available on the subjects that interest them – that’s why they end up specialising.
-
As we gain skills and knowledge, the amount of information we can process increases. If we invest enough time in learning something, we can reach filter like an expert.
-
There can also be expert networks – in some sense that is what the original search engines were, and what mahalo.com is trying now. The problem that the original search engines encountered is that the amount of information available on the web expanded so quickly that it outstripped the ability of the network to keep up with it. This led to the development of google’s search algorithm – an example of one of the versions of mechanical filtering: algorithmic.
-
heingold also provides a pretty good description of the other form of mechanical filtering, heuristic, in his piece on crap detection. Heuristic filtering is based on a set of rules or routines that people can follow to help them sort through the information available to them.
-
Filtering by itself is important, but it only creates value when you combine it with aggregating and connecting. As Rheingold puts it:
-
The important part, as I stressed at the beginning, is in your head. It really doesn’t do any good to multiply the amount of information flowing in, and even filtering that information so that only the best gets to you, if you don’t have a mental cognitive and social strategy for how you’re going to deploy your attention. (emphasis added)
-
I've been seeking a way to explain why I introduce Diigo along with Information fluency skills in the E-Learning for Educators Course. This article quickly draws the big picture. Folks seeking to become online teachers are pursuing a specialized teaching skill that requires an information filtering strategy as well as what Rheingold calls "a mental cognitive and social strategy for how you're going to deploy your attention."

technology of printing did not change for nearly four centuries, but the reading public grew larger and larger, thanks to improvements in literacy, education, and access to the printed word.

would argue that the new information technology should force us to rethink the notion of information itself.
-
continuity I have in mind has to do with the nature of information itself or, to put it differently, the inherent instability of texts.
-
every age was an age of information, each in its own way, and that information has always been unstable.
-
aving learned to write news, I now distrust newspapers as a source of information, and I am often surprised by historians who take them as primary sources for knowing what really happened
-
newspapers should be read for information about how contemporaries construed events, rather than for reliable knowledge of events
-
We live in a time of unprecedented accessibility to information that is increasingly unreliable. Or do we?
-
Instead of firmly fixed documents, we must deal with multiple, mutable texts. By studying them skeptically on our computer screens, we can learn how to read our daily newspaper more effectively—and even how to appreciate old books.

Unbelievers used to dismiss Henry Clay Folger's determination to accumulate copies of the First Folio edition of Shakespeare as the mania of a crank.

When Folger's collection grew beyond three dozen copies, his friends scoffed at him as Forty Folio Folger.

They abridged, expanded, and reworked texts as they pleased, without worrying about the authors' intentions.

o put it positively, there is something to be said for both visions, the library as a citadel and the Internet as open space.

2. Although Google pursued an intelligent strategy by signing up five great libraries, their combined holdings will not come close to exhausting the stock of books in the United States.
-
1. According to the most utopian claim of the Googlers, Google can put virtually all printed books on-line.
-
If Google missed this book, and other books like it, the researcher who relied on Google would never be able to locate certain works of great importance.
-
On the contrary, Google will make them more important than ever. To support this view, I would like to organize my argument around eight points.
-
For books under copyright, however, Google will probably display only a few lines at a time, which it claims is legal under fair use.
-
3. Although it is to be hoped that the publishers, authors, and Google will settle their dispute, it is difficult to see how copyright will cease to pose a problem.
-
But nothing suggests that it will take account of the standards prescribed by bibliographers, such as the first edition to appear in print or the edition that corresponds most closely to the expressed intention of the author.
-
Google defines its mission as the communication of information—right now, today; it does not commit itself to conserving texts indefinitely.
-
it has not yet ventured into special collections, where the rarest works are to be found. And of course the totality of world literature—all the books in all the languages of the world—lies far beyond Google's capacity to digitize
-
Electronic enterprises come and go. Research libraries last for centuries. Better to fortify them than to declare them obsolete
-
7. Google plans to digitize many versions of each book, taking whatever it gets as the copies appear, assembly-line fashion, from the shelves; but will it make all of them available?
-
No single copy of an eighteenth-century best-seller will do justice to the endless variety of editions. Serious scholars will have to study and compare many editions, in the original versions, not in the digitized reproductions that Google will sort out according to criteria that probably will have nothing to do with bibliographical scholarship.
-
8. Even if the digitized image on the computer screen is accurate, it will fail to capture crucial aspects of a book.
-
ts physical aspects provide clues about its existence as an element in a social and economic system; and if it contains margin notes, it can reveal a great deal about its place in the intellectual life of its readers.
-
Rare book rooms are a vital part of research libraries, the part that is most inaccessible to Google. But libraries also provide places for ordinary readers to immerse themselves in books,

I also say: long live Google, but don't count on it living long enough to replace that venerable building with the Corinthian columns.

he research library still deserves to stand at the center of the campus, preserving the past and accumulating energy for the future.
