Start with the question, not the search box
It is tempting to type every question into the nearest search box. But a search engine, a library catalog and a database do different jobs. Choosing between them is less about which tool is “best” and more about what you need to find. Are you trying to understand an unfamiliar topic, locate a particular book or gather focused information for a project?
Before searching, put your goal into one sentence. “I need a simple explanation of how volcanoes form” suggests a different starting point from “I want to borrow a book about volcanoes” or “I need articles about how volcanic ash affects air travel.” If you are unsure what you need, that is fine too: an initial search can help you learn the vocabulary to use in the next tool.
Use a search engine to explore and find your bearings
A general search engine is useful when you need a quick introduction, a definition or ideas for narrowing a broad question. It can lead you to museums, educational organizations, publishers and other sites. It can also help you check a book’s full title or an author’s name before looking for that item elsewhere.
Its convenience comes with a catch: search results can mix helpful explanations with advertisements, outdated pages and material written for very different audiences. A result near the top is not automatically the best source. Open the page and ask who made it, what its purpose is and whether it gives enough detail for your task. For a school assignment or a careful comparison, treat the first search as a way to develop better questions, not necessarily as the finish line.
Use a library catalog to find books and other holdings
A library catalog tells you what a particular library or library network lists in its collection. Start there when you have a title or author in mind, want a book-length treatment of a subject or need to know whether an item is available to borrow. Depending on the library, the catalog may also list ebooks, audiobooks, films and other materials.
Subject searches can reveal promising books you would not find by guessing titles. Try a broad term first, then inspect the descriptions and subject headings on useful records. If “gardening” brings back too much, a search such as “container gardening” may get you closer. Remember that a catalog record usually describes an item rather than providing its full contents. If you need a specific answer inside a book, look for a table of contents, index or preview when one is available.
Use a database for focused articles and reference material
A database is a searchable collection assembled around certain types of material or subjects. Through a library, you might encounter databases of magazine and newspaper articles, reference entries or academic writing. They can be especially useful when you need several sources on a focused topic, want to compare viewpoints or have been asked for a particular kind of article. What is included varies by database, so check its description before diving in.
Database searching often rewards a little experimentation. Start with two or three important words rather than a whole sentence. If you are looking at sleep and teenagers, try both “teenagers” and “adolescents”; different writers may use different terms. Filters for date, material type or subject can reduce a crowded results list, but use them thoughtfully. A filter that is too narrow might hide a useful source. Some libraries require a library card or sign-in for access outside the building.
Move between tools, then judge what you found
These tools work well together. You might begin with a search engine to learn that a topic has several names, use those terms in the catalog to find an accessible book, then search a database for articles on one question the book raises. Or you might start with a catalog record, notice a useful subject heading and carry that phrase into a database search. Changing tools is not starting over; it is using what you have learned.
Whichever route you take, pause before relying on a result. Does it actually answer your question? Can you identify who created it and why? Is it written at a level you can understand without losing the detail you need? If two useful-looking sources disagree, compare what they are discussing and how they support their claims rather than choosing the easier answer. The strongest search habit is not knowing the perfect place to look first. It is recognizing when your current tool has taken you as far as it can.
