Chapter 2: Searching
2.1 Three categories of search tools
It might be tempting to do all your information-gathering with a single internet search. However, you may need to use many types of sources, not all of which will be covered by your basic search engine, like Google. Keep in mind that research takes time, thought, and energy, and there will often be more than one place to search or tool to use. Effectively locating and using information requires familiarity with three primary categories of search tools: search engines, library discovery tools, and databases/indexes.
Search tools provide structure for information searches. They include information about a resource’s content (like what topics are discussed) and how it is packaged (like the format). While all of these tools are typically accessed via the internet, they function in different ways and search different things. Some search tools overlap in coverage (e.g., databases AND search engines will find journal articles), but each has unique features that can help you find particular types of sources. The search tools complement each other and each is a vital piece in the information-seeking puzzle. Below is a breakdown of the different search tools we’ll discuss in this class.
Search engines
Search engines are tools that search the internet using the keywords you provide. Some popular search engines are Google, Bing, DuckDuckGo, and Yahoo.
Search engines are best for finding:
- websites
- news sources
- images
- statistical information from government sources and some other organizations
- most of the information on the open web
Library discovery tools
Library discovery tools connect users to, essentially, all the resources available via the library. At NKU, the discovery tool is used every time you search “All Resources” from the library’s homepage.
Library discovery tools are best for finding:
- books and eBooks
- encyclopedias
- scholarly journal articles
- other materials that a specific library owns or provides access to
Databases and indexes
Databases and indexes help you find scholarly materials such as journal articles, book chapters, and more. These tools use the keywords you provide to search through details about scholarly sources (such as topics, authors, and titles), allowing you to find targeted results. NKU’s Steely Library provides an A-to-Z list of databases you have access to as an NKU student.
Databases and indexes are best for finding:
- scholarly journal articles and summaries of articles you can request through Interlibrary Loan
- books chapters
- newspaper articles, including many historical newspapers
- highly specialized types of documents used in certain subject areas
