Information is all-pervading!
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.
• Gleick, James (2011). The Information: A History, a Theory, a
Flood (Kindle Locations 134-138). Pantheon. Kindle Edition.

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.

Theory, a Flood (Kindle Locations 141-143). Pantheon.
Kindle Edition.

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.
• ODLIS: Online Dictionary for Library and Information Science

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

Do you know what information is?

What is it?
 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.
 LIB 120 - What is Information?
 University Libraries » LibGuides @ URI » LIB 120 - What is
Information?
10
Characteristics of information
 Information comes in all shapes and sizes. Knowing
some of its characteristics will help you better
identify your information need and evaluate what
you are receiving.
• Factual vs Analytical
• Subjective vs Objective
• Current vs Historical
• Scholarly vs Popular

Understanding the information
universe

Tutorial: Information Formats
12
Information Types
 That is, what the information looks (or sounds) like
 Textual
 Bibliographic
 Numeric
 Graphical
 Audio
 Multimedia
13
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.”
• Gleick, James (2011). The Information: A
History, a Theory, a Flood (Kindle Locations
7201-7205). Pantheon. Kindle Edition.
13
14
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.
• Gleick, James (2011). The Information: A History, a Theory, a Flood
(Kindle Locations 7587-7588; 7592-7595). Pantheon. Kindle Edition.

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

What is information?

  • 1. What is Information? And what do we do about it? LIB 640 Information Sources and Services Summer 2014
  • 4. 4 Information is all-pervading! 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. • Gleick, James (2011). The Information: A History, a Theory, a Flood (Kindle Locations 134-138). Pantheon. Kindle Edition. 4
  • 5. 5 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. • Gleick, James (2011). The Information: A History, a Theory, a Flood (Kindle Locations 141-143). Pantheon. Kindle Edition. 5
  • 6. 6 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. • ODLIS: Online Dictionary for Library and Information Science
  • 7. 7 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
  • 8. 8 Do you know what information is? http://vimeo.com/3248432
  • 9. 9 What is it?  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.  LIB 120 - What is Information?  University Libraries » LibGuides @ URI » LIB 120 - What is Information?
  • 10. 10 Characteristics of information  Information comes in all shapes and sizes. Knowing some of its characteristics will help you better identify your information need and evaluate what you are receiving. • Factual vs Analytical • Subjective vs Objective • Current vs Historical • Scholarly vs Popular
  • 11. 11 Understanding the information universe 11 FLCC Library » LibGuides » Library Research Tutorial: Information Formats
  • 12. 12 Information Types  That is, what the information looks (or sounds) like  Textual  Bibliographic  Numeric  Graphical  Audio  Multimedia
  • 13. 13 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.” • Gleick, James (2011). The Information: A History, a Theory, a Flood (Kindle Locations 7201-7205). Pantheon. Kindle Edition. 13
  • 14. 14 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. • Gleick, James (2011). The Information: A History, a Theory, a Flood (Kindle Locations 7587-7588; 7592-7595). Pantheon. Kindle Edition. 14
  • 15. 15 Is there help to be found from librarians? • If so, how should it work? Can we help?
