4. Information is all-pervading! 4
James Gleick:
• For the purposes of science,
information had to mean
something special. . . . A rite
of purification became
necessary.
• And then, when it was made
simple, distilled, counted in bits,
information was found to be
everywhere. [Claude] Shannon’s [information] theory
[1948] made a bridge between information and
uncertainty; between information and entropy; and
between information and chaos. It led to compact discs
and fax machines, computers and cyberspace, Moore’s
law and all the world’s Silicon Alleys. Information
processing was born, along with information storage and
information retrieval. People began to name a successor
to the Iron Age and the Steam Age.

Why Shannon?
Gleick:
• We can see now that
information is what our world
runs on: the blood and the fuel,
the vital principle. It pervades
the sciences from top to bottom,
transforming every branch of
knowledge. [Shannon’s]
Information theory began as a
bridge from mathematics to
electrical engineering and from
there to computing.

Information, more precisely
defined?
Information
• Data presented in readily comprehensible form to
which meaning has been attributed within the
context of its use. In a more dynamic sense, the
message conveyed by the use of a medium of
communication or expression.
• Whether a specific message is informative or not
depends in part on the subjective perception of
the person receiving it. . . . Compare with
knowledge.

7. Another view of “information”

Comment from a former faculty member at
the College of Library and Information in Oslo,
Norway:
 ―. . . you know, there’s
nothing as fluid as the
information concept; it’s
like . . . an amoeba!‖
From a group interview for Dr.
Johan Koren’s dissertation
research, Fall 1989

What is information?
 According to the International Encyclopedia of Information
and Library Science, information is ―best seen as holding
the place in the spectrum between raw data and
knowledge. Seen in this way, information is an assemblage
of data in a comprehensible form capable of
communication and use: facts to which meaning has been
attached.‖
 In this sense, almost everything could be information -
facts (events, concepts, objects, etc.) that carry meaning
and can be communicated.

Characteristics of information
 Knowing the character or type of information can
help you to identify its origin and use. There are
several kinds of information that can be useful for
different reasons.
• Factual Information
• Analytical Information
• Subjective Information
• Objective Information

Information formats
• When information is recorded and stored, it
exists in a physical form called a format.
There are three broad categories of format:
• Print – paper
• Audio-visual - film, audiotape, videocassette,
slides, microfilm, vinyl records, etc.
• Electronic – information that’s recorded, stored
and retrieved using computer technology.
Examples include CD’s, DVD’s, and all online
sources.

 Textual
 Bibliographic
 Numeric
 Graphical
 Audio
 Multimedia

The result?
Gleick again:
• After ―information theory‖ came to be, so did
―information overload,‖ ―information glut,‖
―information anxiety,‖ and ―information
fatigue,‖ the last recognized by the OED in
2009 as a timely syndrome: ―Apathy,
indifference, or mental exhaustion arising
from exposure to too much information, esp.
(in later use) stress induced by the attempt to
assimilate excessive amounts of information
from the media, the Internet, or at work.‖

The solution?
Gleick has none but hard work:
• No deus ex machina waits in the wings; no man behind
the curtain.
• As ever, it is the choice that informs us (in the original
sense of that word). Selecting the genuine takes work;
then forgetting takes even more work. This is the curse of
omniscience: the answer to any question may arrive at the
fingertips—via Google or Wikipedia or IMDb or YouTube
or Epicurious or the National DNA Database or any of
their natural heirs and successors—and still we wonder
what we know.

Can we help?
Is there help to be found from librarians?
• If so, how should it work?
