Mooer's Law

Mooers’ Law: An information retrieval system will tend not to be used whenever it is more painful and troublesome for a customer to have information than for him not to have it.

Moore's law

The observation made in 1965 by Gordon Moore, co-founder of Intel, that the number of transistors per square inch on integrated circuits had doubled every year since the integrated circuit was invented. Moore predicted that this trend would continue for the foreseeable future. In subsequent years, the pace slowed down a bit, but data density has doubled approximately every 18 months, and this is the current definition of Moore's Law, which Moore himself has blessed. Most experts, including Moore himself, expect Moore's Law to hold for at least another two decades.

William Katz- Guidelines in evaluating reference services

  • Be approachable
  • Show interest
  • Conduct a reference interview
  • Conduct a search
  • Follow-up

Nine methods of subject searching from the Oxford Guide to Library Research by Thomas Mann

  1. Controlled vocabulary searching
  2. Browsing and scanning subject-classified bookstacks
  3. Keyword searching
  4. Citation searching
  5. Related-record searching
  6. Searching through published bibliographies
  7. Boolean combination searching (with some other computer manipulations)
  8. Using the subject expertise of people sources
  9. Type of literature searching

Evaluating Reference Sources

(C. Trax - from compssummer2007 wiki)

Here is a mnemonic devise I developed to help me evaluate reference sources and serials. See page 312 in Reference and Information Services by Richard Bopp for a more in depth explanation of each point, and be sure to add your own details.


  • Format: What is the physical makeup of the information package? Book? Microform? CD?
  • Order (Arrangement): Is the work a continuation of a series? Where will it fit on the shelf? How is the information accessed?
  • Relation to similar works: How does this item relate to other items in the collection? Does it contribute in a different way? Does it replicate?
  • Features: What is unique about this item?
  • Authority: What is the education and experience of the editors, contributors, and organization? Do they have a history of providing useful and reliable information on the topic in hand?
  • Cost: How does the item fit in the over-all budget? How often will it need to be replaced to remain current?
  • Treatment: Who is the audience? What is the quality of the writing, statistics etc.
  • Scope: What is covered and to what degree? Time period; Geographic region; currency; content.
