week 5

Hello..

Week 5 with new topic..
In this week, I have learnt about apply selected tools and strategies to locate information. My lecture taught us on clearly about this topic. As we know, keywords usually give us more resources or a broader search. Selecting keywords in our research can make our terms become broader and narrower.

Besides, we also learnt about subject headings. Subject headings, which use a standardized vocabulary, usually give us more specific resources on our topic. The official words used by catalogs and many indexes to identify all of the books or articles dealing with a particular topic are called subject headings. Subject headings can be one word, two or more words, a phrase, a city, a country, a person, etc.

SESSION 1 – brainstorming for search terms

Examples of subject headings are:

• Library Subject Headings:

Used as the "official vocabulary" of the Libraries catalog as well as many other library catalogs.

• Science Subject Headings:

Used to describe the content of documents in the Library at AIU as well as in catalogs of other medical and health sciences libraries.

• Thesaurus of Psychological Index Terms:

This controlled vocabulary is used by American Psychological Association indexers to describe the content of documents in the database.  These subject headings are sometimes called index terms or descriptors.  The library has copies of the printed volume and the thesaurus is also available online, searchable from within the database.

SESSION 2 AND 3

Then, we also learnt about Boolean operators. This topic is quite an interesting to explore. This topic makes us easy to find the information we need.

Boolean operators is (named for George Boole, 1815-1864, a mathematician) combining terms such as AND, OR, and NOT used in building a search statement or in putting several sets together.
Allows us to group words together in an electronic database or environment such as the World Wide Web to receive a number of different types of results.

Words that connect a search that may add or subtract a concept to our search.

limit the search

expend the search

exclude the search

difference between three of them..

that all for this week..keep smiling..see you next post!!
