Third
topic is started with third main point of big-6. Location and access is a main
step in big-6 model that tell us where we can find relevant and reliable
information by using different sources. When we search on internet then we need
a search tool.
Search Tool:
Is a utility on internet
to find out the information among thousands of documents. Search tools are
classified into three types.
Library
catalogue
Internet
directory or search engine
Database
1. Library
catalog:
It is a lesson that
provides information library online system and how to use it. For example, AIU
library catalog. It tells us to find books, periodicals audiovisuals. It can
be book catalog, card catalog or online catalog. Online catalog in AiU is
called OPAC. It is stand for online public access catalog. This OPAC system is
known as ITALIC. This provides information about books and many more
information sources and facilitates students. Different universities have
different OPAC system.
The
OPAC is provided by VTLS (virginia tech library system). This is a company that
provides library automation software and services mostly to universities and
governments. The new name of VTLS is “Chamo”. This system allows students to
interact with library management to tell them what they have found new on
social media. This system also allows students to share information on Facebook
or twitter. Students can tag others and can get more interaction. this system
also can be accessed by mobile devices.
ITALIC
provides two types of search. One is general search and other is advanced
search. In general search, we can write books name, author name. But in advance
search, we can purify our search. We can find by years, author, title, ISB ,
ISSN, LCCN, UPC and control number. This
system also allows us to change country and language to find books and other
materials. There are many books in AiU library with different languages.
Internet:
Internet is a network of
interconnected networks that allows billions of people to communicate each
other. It is also called “Global information system”. There are two ways to
find information on web by
Search
engine
Subject
directories
Search
engine is a largest database that provides
quick and reliable information. We type by keyboard about related topic and
search engine will find the related website. Turbo 10, Google, Yahoo, Surfwas
are the examples of search engines.
Subject directories in general are
smaller and selective than search engines. They use categories to focus your
search, and their sites are arranged by categories, not just by keywords. These
may be called Internet catalogues. They are always compiled by people (rather
than indexed automatically) who organize information according to a
classification system. Examples,
Library
search.com
Google
scholar
Online
database:
Collection of
computerized information such as articles, books and graphic multimedia that
can be searched by online. Online database also provide facility to publish
magazine or journals, newspapers and other information sources. For examples,
PROQUEST
Science

Boolean search allow user to combine words and phrases using symbolic logics called Boolean search to refine, define, limit and broad the search. There are three operators of Boolean search
AND

using OR, it will expand the search
3.Truncation&
Wildcards:
Truncation
and wildcards broaden our search abilities by allowing us to retrieve multiple
spellings of a root word or word stem, such as singular and plural forms.
A wildcard AND Truncation is a
special character, such as an asterisk (*), question mark (?), or pound sign
(#), that replaces one or more letters in a word.
