INTRODUCTION
This course builds upon basic knowledge and skills in using the Internet and
online resources to find information for clients. For participants who would like
more information about the Internet the BHP Billiton skills.net course ‘Getting
Started’ is recommended. It is available on State Library’s website at
www.slq.qld.gov.au
i) The course
The aim of this course is to assist library staff to link their community with
quality information that meets their needs. To achieve this aim we will look at
the changing information environment, issues impacting on the ability to
provide clients with the best possible information available and strategies to
keep up to date.
ii) The objectives for this course are that at the conclusion of this training all
participants will be:
2
•
aware of issues which can impact on the ability to meet the
information needs of your community
•
able to identify the most appropriate method/resource to find
information for clients
•
aware of the changing information environment and how to keep
up to date professionally

ISSUES THAT CAN IMPACT ON THE ABILITY TO
LINK CLIENTS WITH RELEVANT INFORMATION
Knowledge of the information environment
•
Amount of information available - terms such as the “information
explosion” and “information age” indicate that we have at our disposal
(mostly thanks to the Internet) large quantities of information. How do we
navigate this quantity of information to find the best to suit our needs?
•
Kinds/formats – as well as our traditional print resources, we now have
access to online resources in a variety of formats eg PDF (portable
document format). We have access to web resources via search
engines, subject directories, meta-search engines, online databases.
Knowledge of these tools enhances our information seeking process.
•
Availability – we can now access information 24 x 7, no longer being
limited to the library and library opening hours. People can access
information from home or anywhere they have Internet access.
Changes in society
•
Workplaces/ workplace skills are changing and are affecting people’s
needs for information and the skills needed to access information. There
are fewer unskilled jobs available and very few jobs that require no
knowledge of information technology. Increasingly people need IT skills
to survive and the nature of fewer unskilled jobs means a lifetime of
learning to remain employable.
•
Personalization – there is an expectation now that everything can be
tailored to individual needs. This has flowed onto the provision of
information eg My Yahoo!, MyEBSCOhost, My e-bay
•
Knowledge economy – information in our society is now a commodity.
Those people who can access information effectively are at an
advantage. Library professionals play a key role in building the
knowledge economy in our communities.
•
Client expectations – client’s information expectations have risen. Due
to many factors, including misconceptions that anything can be found on
the Internet, clients do not expect to walk into a library and come away
with no information. What can we provide for our clients if we cannot find
the exact answer?

Knowledge of your community
•
Information literacy – providing information is not enough – access and
information literacy skills are needed. How skilled is your community?
•
What are they using the Internet for? For example: finding information,
online banking, helping children with assignments. Knowledge of your
community will inform the way you promote information for them.
Awareness of what exists
•
How do you find out about new information? Do you belong to a
professional group who updates you? Are you on mailing lists? Do you
have good knowledge management practices in your area?
Your own knowledge – is it dated?
•
Your ability to stay up-to-date with the latest trends and technology in
information delivery directly impacts on the end product you provide for
your clients.
Your ability to evaluate information on the Internet
•
Information on the Internet ranges from high quality, informative
professional resources to anything and everything an individual can post.
What are the things you need to be aware of to assess the quality of a
website?
Reference Interview – are you making the most of the time?
•
4
Do you know exactly what your client is seeking? Often your client
will ask you for something at the information desk when really they want
something quite different. Finding out exactly what your client wants
impacts on the appropriateness of information they will receive.
OPAL Training Project
State Library of Queensland

Your reference desk and computer set-up
•
Can you quickly locate information? Have you got a second window
open to access subject directories or your favourite search engine?
•
Does your circulation staff know when to refer queries to professional
staff?
Knowledge of latest software etc so that clients can use sites
•
To be able to use sites to their full potential software may need to be
loaded on your PC eg QuickTime, adobe, shockwave. Is this an issue for
security on your computers? How easy is it to get permission to have this
software installed? Do you really have a good understanding of how your
computers are set up or is this knowledge in the IT department of your
organization?
Barriers – policies/charges
•
Are your photocopying/ Internet access charges prohibitive to finding
information? How do charges and policies cause barriers to providing the
best information for your clients needs?

SEARCH OPTIONS
2.1
SUBJECT DIRECTORIES
Defining Subject Directories
•
Subject directories are organized by humans. Web sites are manually
selected based on predetermined criteria, therefore there is a high degree
of accuracy and quality in the results.
•
Subject directories organize chosen web sites hierarchically into lists of
subjects. These general subjects are then broken down into subcategories.
•
There are commercial (www.Yahoo.com) and non-commercial (academic
and professional) (netlinks.slq.qld.gov.au) subject directories.
•
Commercial directories or portals are aimed at the general community eg.
Looksmart. Website developers often pay a fee for inclusion in such a
directory.
•
Academic and professional directories are compiled by experts and usually
contain links to relevant and useful information.
•
Try to find out the criteria adopted by subject directory developers for web
site inclusion. If the web site includes information about criteria and
selectors, the information found may be more trustworthy than web sites
included in directories where this information is not made freely available
to users. Netlinks is a good example of criteria for selection.
http://netlinks.slq.qld.gov.au/about.htm
Advantages
•
Good for browsing. Useful when you want to see what range of
information is available on a topic – akin to reading the content pages of a
book.
•
Compiled by human editors so results are quite accurate.
•
Fewer hits than when using a search tool but results are likely to be more
accurate.
Disadvantages
•
Be wary about the reason for the inclusion of certain web sites in
commercial subject directories.
•
Compiled by human editors who may have different ideas about which
subject category a topic relates to.
6
OPAL Training Project
State Library of Queensland
4 February 2008
When to use a subject directory
•
When you want an overview of the categories of information available on a
subject eg. Cooking, dogs, planets.
•
When you want to retrieve a list of sites relevant to your topic, rather than
numerous individual pages contained within those sites.
•
When you are trying to decide on a topic eg. One of the planets in the
solar system.
How do I use them?
•
Simply choose from the list of subjects the one that best suits your search.
•
Then work through the various lists of sub-categories until you are
presented with a list of relevant web sites.
For Example – If you were searching for web sites about the planet
Mars, you would select the Subject Area “Science” and then choose the
pertinent sub-categories.
Artificial life
Choose from
sub-categories
Astronomy
Astronomers
Chemistry
Eclipses

SUBJECT GATEWAYS
Defining Subject Gateways
•
Is a web site that provides searchable and browsable access to online
resources focused around a specific subject
•
Resource descriptions are usually created manually rather than being
generated via an automated process
•
Because the resource entries are generated by hand they are usually
superior to those available from a conventional web search engine
•
The core activities of resource selection and description rely on skilled
human input (by librarians, academics and experts). Thus they are
characterized by quality control
When to use
•
When seeking specialized knowledge in a particular subject area
Australian Subject Gateways
Weblaw
www.weblaw.edu.au
•
Is a co-operative subject index to Internet resources for Australian legal
researchers including lawyers, students, researchers and lay
professionals
•
Participating organisations take responsibility for a subject area/s, and

2.3
SEARCH ENGINES
Defining Search Engines
•
Search engines consist of three parts:
1. Robots, bots or spiders that collect links
2. A database where the information is stored; and
3. Technology which allows users to search the index and return the
results
•
Robots crawl through the Internet and locate web pages to index for
inclusion in the database
•
Robots choose which words to index based on their location on the page
and how frequently they are repeated throughout the document (unless
keywords are specified using metadata tags). Some robots will index
every word in the text except those listed on the stop list such as “and”,
“the”, and “a”. Some databases use another process called stemming that
removes suffixes (-s, -es, -ed) and may also remove (-able, -ability, -ness)
from keywords when creating the indexes.
•
The searcher then enters a search query into the front-end search facility,
usually in the form of a search box
•
If the search is successful, a list of results is presented, ranked in order of
their relevance to the search terms entered. Ranking systems used by
search engines vary. Ranking is based on an algorithm or a set of rules.
Most use “fuzzy and” combined with factors such as how often your terms
occur in documents and whether in the title or how near the top of the text.
(“Fuzzy and” means that documents which contain all of the search terms
are displayed first followed by documents that contain only some of the
search terms).
•
Google determines relevance by analyzing how many other web sites link
to each web page and the importance of those pages (eg. A government
site would be rated as more highly than a porn site). It also ranks sites
according to how frequently they have been accessed by previous
searchers.
•
No one engine searches the entire web
•
Highest ranking search results can vary much between search engines.
Try the research tools, http://ranking.thumbshots.com and
www.jux2.com to compare the ranking of search results from different
search engines.
•
No two search engines are exactly alike
•
Using a search engine is like using the index of a book
14
OPAL Training Project
State Library of Queensland
4 February 2008
Advantages
•
Very easy to search for topics, simply type in a search word or phrase
•
The ranking system allows you to view the most relevant search results
quickly
Disadvantages
•
As there is no human intervention, the accuracy of some of the pages
found can be dubious. Some of the pages displayed may have no
relevance to the initial search query.
•
Web sites that include different terminology than the terms entered in the
search will not be found
When to use Search Engines
•
When you are undertaking a specific search
•
When you are searching for an obscure topic
•
When you want to take advantage of the latest retrieval technologies
Examples of General Search Engines:
All the web
www.alltheweb.com
•
Uses Yahoo!’s index and is powered by Yahoo!
•
Focuses on web search but also searches news, video, pictures, mp3
files, ftp files audio

Yahoo! Search
www.search.yahoo.com
•
Since February 2004 Yahoo! has used it’s own technology to provide
crawler based listings (from 2002 to 2004 it relied on Google’s results)
•
Searches the web exclusively, does not search directory
•
My Yahoo! Search allows personalisation through sign in feature and
saving results, catagorising results, blocking sites and searching within My
Web
•
Is the closest competitor to Google in the US – in July 2004 the
percentage of searches measured in the US were 31.5% by Yahoo!
compared to 41.6% by Google (Nielsen//Net ratings survey)
Hotbot
www.hotbot.com
•
Launched in May 1996 by Wired Digital then purchased by Lycos in 1998
•
Developed a strong following in the early years for quality and
comprehensiveness
•
Search features suffered in 1999/2000 when Lycos focused on developing
portal content
•
Lycos refocused on search capabilities in 2001
•
Also provides access to Google and Ask Jeeves but it is not a meta search
engine in that it cannot blend the results of these search engines together

Ask.Com
www.ask.com
Initially gained fame in 1998 and 1999 as the “natural language” search
engine that let you search by asking questions and responding with what
seemed to be the right answer
•
Hasn’t always relied on technology for results. At one point had up to 100
editors who monitored search logs and went onto the web to locate the
best sites to match the most popular queries
•
Today uses crawler based technology and results come from Teoma
•

META SEARCH TOOLS
Defining Meta Search Tools
•
Metasearch tools allow you to conduct a search at a site which transmits
your search to a number of individual search engines. Essentially, you are
searching the indexes of a number of search engines and the entries of
some directories.
•
There are many search engines and new ones emerging all the time.
Meta-search engines are getting better and offering some good features.
Advantages
•
Able to search numerous individual search tools at once
•
Use of new technologies such as clustering allow for results to be
displayed in more meaningful ways
Disadvantages
•
Meta search tools can be prone to timing out due to the size of the search
•
The meta search engine may not support all of the search features offered
by individual search tools
•
Meta search tools are only as good as the search engines they search
When to use Meta Search Tools
•
If you have already conducted an unsuccessful search using one or two
search engines select a meta search tool that searches other directories
and search engines
•
Use meta search tools when you wish to conduct a fast overview of the
information available on a topic
•
Meta search tools are also useful when you are searching for an obscure
topic because you cover more than one search tool
Examples of Meta Search Tools:
SurfWax
www.surfwax.com
•
Searches against major search engines
•
Can customise in My Preferences after signing up at a free or higher level
•
Offers a variety of features to help you dig deep into your results
•
Searches results can be saved in Info Cubby for future use

THE DEEP WEB
Defining the Deep Web
•
Also called the Invisible Web
•
It is the part of the World Wide Web that is not indexed by search engines.
Search robots or spiders are unable to carry out the indexing process on
many of the Deep Web sites because of their formatting or because there
are no links to the site.

Objects that make up the Deep Web are either stored in databases or
produced in non-HTML formats. This used to include formats such as
PDF files, images and sound. Objects still part of the Deep Web include
formats such as macromedia flash. Because of the highly competitive
environment of search companies and the advantages of being able to
index more of the Deep Web, what search engines are able to locate and
index is continuously changing and developing.

An estimated 500 times larger that the known “surface” World Wide Web
•
It is also estimated to be the largest growing category of new information
on the Internet. It has been reported recently that the Deep Web is made
up of “550 billion web pages, while the surface web is made up of a mere
1.2 billion” (Gliddon, 2001:64).

The key to locating information on the Deep Web is to be aware of the
gateways to these resources. A number of useful web sites for locating

DATABASES
•
Commercial databases are collections of information presented
electronically. Databases range from library catalogues and white-pages
directories to several billion records contained in the larger news
databases.
•
The commercial information environment began in the 1960’s. It has
developed into a valuable but expensive research resource.
•
Databases are arranged into either full-text or bibliographic information (or
a combination of both)
•
Databases have their own particular idiosyncrasies and require
individualized searching techniques
Full text databases
•
Access to databases has shifted to provide online access via the Internet
•
Often with Internet access, a site will offer free searching but will charge
for the articles. In the main, full text retrieval is a commercial enterprise.
•
Access to full text information is provided to the public by libraries that take
out subscriptions to these services
•
State Library provides access to several online databases for all
Queensland public library members. These databases provide access to
full text newspaper articles, magazines and reference books.
•
Information about the databases that State Library subscribe to and that
are available Queensland wide to public library members begins on page
