Module 2: AND THE TEXT BOOK IS HERE!

Posted by arlekeno on July 18, 2012

Reading From Chapter 14 of  “Organising Knowledge in a Global Society (Princilpes and practices of libraries and information centres)” Revised Edition 2008 By Philip Hider with Ross Harvey…. Local Systems and OPACS.

An Integrated Library system (ILS) Definition pg 277

  • An ILS relies on the same data in a single database to provide four basic functions (aquisitions, cataloguing, circulation, and online public access catalogue).
  • The Database comprises bibliographic data (e.g., cataloguing records) as well as other data neccesary to carry out library-related functions (e.g. borrower files for circulation purposes)

The effectiveness of all the modules will stand or fall on factors such as the quality of the records in it and its ease of use.

I like this on OPAC T; the Goal of teh 4th Generation OPAC is to get patrons to prefer a library search to google… That is a BIG CALL!  Google has more money than libraries, but we need to this, because poor search skills leads to little success, leads to google.

Ok, just read chapter 14, now to read Chapter 8 on Controlled Vocabulary, I think here of the SCIS subject headings. Another 30 pages and references to previous chapters the Modules have not asked us to read yet…. Hmm, I think I will call it quits for a while.

A lot of talk about thesauri, and a lot of acronyms.

Activity time, .. oops, server is overloaded… oh well, shall have to wait till tomorrow I guess.

Ok, on now, after a day break, Playing around with it all. http://www.getty.edu/research/

Here’s a brief explanation of why these differences in search results using different internet search engines occur.

First, you need to know about the difference between search engines and directories.

  • Search enginesuse software called web crawlers to gather words from sources such as web page titles and site content. These words are compiled into indexes. Users search the results located by the web crawlers by searching the indexes.
  • Directories of descriptions of websites are compiled from lists of sites reviewed by editors. Users search these descriptions. Generally speaking, a well-designed site with extensive and original content is more likely to be listed in directories. (Google is famous for applying another major criterion: the extent to which pages are linked from other websites.)
  • Search engine softwaresifts through the millions of pages recorded in the index, finding matches and ranking these matches in order of relevance. This relevance ranking is determined in two main ways: by position of the words, and by their frequency.
  • Position: keywords appearing in the title of a web page, or in the first few paragraphs of text, are considered to be more relevant to the topic than words appearing in other positions on the page.
  • Frequency: keywords which appear more frequently in a web page are considered to be more relevant than other words, and so the web pages which contain them are considered more relevant.

HOW DID I NOT KNOW ABOUT THIS SITE!!! http://searchengineshowdown.com/

Activity

The Berkeley Digital Library SunSITE provides information and support to digital library developers worldwide. It is also an excellent starting point for looking at a range of digital libraries. Select several digital libraries of interest to you. Browse through them, thinking about these questions as you go:

  • Is this a ‘library’ in the traditional sense of the word?
  • What categories of materials (e.g. archival material, museum objects, library material) does it provide access to?

Anyway, I am off to read Chapter one of the text, and then I will up to date for the week, FINALLY!
