Physical Resources

These are tangible materials found in libraries and archives, including:

• Books and textbooks – foundational academic sources
• Journals and magazines – current research and scholarly articles
• Reference materials – dictionaries, encyclopedias, and atlases
• Archives and special collections – unpublished materials such as manuscripts, letters, and photographs

Physical libraries remain essential because some information exists only in printed form, and many libraries now offer both physical and digital materials.

Digital/Online Resources

These include electronic materials accessible through the internet:

• E-books and e-journals – digital versions of printed works
• Academic databases – organised collections of scholarly articles
• Online catalogues (OPAC) – digital indexes of library holdings
• Open-access repositories – freely available academic materials

Using the Online Public Access Catalogue (OPAC)

OPAC is a digital catalogue that allows you to search a library's collection from any computer or mobile device with internet access. Through OPAC, you can:

• Search for books, journals, and other materials by title, author, or keyword
• Check item availability and location within the library
• Reserve or request materials
• Access digital resources remotely

Understanding the Dewey Decimal Classification (DDC)

Most school and public libraries organize books using the DDC system, which assigns a unique number to each subject area. For example:

• 000–099: General knowledge (encyclopedias, computer science)
• 100–199: Philosophy and psychology
• 300–399: Social sciences (economics, education, law)
• 500–599: Natural sciences and mathematics
• 600–699: Technology and applied sciences
• 800–899: Literature and languages

Knowing the DDC number for your topic helps you locate relevant books quickly on the shelves.

Keyword Searching

Keywords are the main words or phrases you enter into a search engine or database. To get relevant results:

• Be specific with your terms (use "cellular respiration" rather than just "respiration")
• Use quotation marks for exact phrases: "cell division"
• Avoid overly broad or narrow terms

Boolean Operators

These logical operators help refine your searches:

• AND – narrows results by requiring both terms: business AND management
• OR – broadens results to include either term: internet OR web
• NOT – excludes unwanted terms: business NOT marketing

You can combine operators using parentheses for complex searches: ("business" OR "commerce") AND "management"

Truncation and Wildcards

These techniques find word variations:

• Truncation (using *) finds words with the same root: educat* finds "education," "educate," "educational"
• Wildcards (using ?) replace single letters: wom?n finds "woman" and "women"

Worked Example

Scenario: You are researching "Gender equity and equality in Tanzania" for a project.

Step 1: Formulate keywords

• Primary keywords: gender equity, equality, Tanzania
• Related terms: women's rights, gender equality, East Africa

Step 2: Apply Boolean operators ("gender equity" OR "gender equality") AND Tanzania

Step 3: Use truncation women* AND Tanzania (finds women, woman's, women's)

Step 4: Search in databases Try searching in Google Scholar, JSTOR, or local university databases using your formulated query.

Before using any source, assess its reliability by checking:

1. Publication date – Is the information current for your topic?
2. Author credentials – Does the author have academic qualifications or institutional affiliation?
3. Peer review – Is the source from a peer-reviewed journal?
4. Objectivity – Is the source biased or presenting balanced perspectives?

Always acknowledge your sources to avoid plagiarism. Use citation management tools or follow referencing styles (APA, MLA) as required by your institution. Remember that proper citation demonstrates academic integrity and strengthens your work.

When working on a Form 6 project about Tanzania's tourism industry, you will use library resources to gather academic sources. For instance, you might search the school library's OPAC using DDC classification 338 (economics) to find books on tourism, then use Google Scholar with Boolean operators like tourism AND Tanzania AND economic development to find journal articles. Properly citing these sources in your project demonstrates academic honesty and prepares you for university research, where these same skills are used for dissertations and thesis writing.
