How to efficiently search online databases for academic research

How to search online databases

Libraries associated with universities provide access to plenty of online research databases that can yield good results when using the right keyword searches. They are among the best sources to turn to when you need to find articles from scholarly journals, full-text articles, books, and periodicals.

Searching an online academic database is much like searching the internet, but the hits returned will be published scholarly articles and other documents depending on the subject. Academic databases are different from generic search engines though, and that's why we have compiled a series of tips to get you started on using academic search engines specifically.

1. Use the campus network to access research databases

Most of the academic databases cannot be accessed for free! As authoritative resources, these multi-disciplinary databases are comprehensive collections of the current literature on a broad range of topics. Because they have a huge range of publications, public access is sometimes restricted.

Your institution needs to pay for staff and students to access journals, books, papers, and more, and that's why you can only use them when you are on the on-campus network. Nonetheless, there are highly comprehensive resources like EZProxy that allow you to also access your library's resources and online collections from your home network.

Check out our list of EZProxy connections to see if your institution provides such as service.

It's 2.5 million articles that are published EACH year. Make sure to search the right, comprehensive database for the reference you need, which is pertaining specifically to your topic, otherwise, you will have to screen too many unrelated papers that won't give you the reference you want.

Ask a librarian or check your library's brief overview of which databases you have access to. If you do not know where to start, you can check out the three biggest academic database providers:

3. Set up the search parameters within the database to be as narrow as possible

Start with one database. Narrow your search terms down to get the most pertinent information from the scholarly resources you are reviewing. Determine which options are available to do that, for example narrowing the search by only including articles within a specific date range, or uncheck certain types of journals or magazines that are included in the database but have nothing to do with your topic.

Make sure to also use very specific keywords when searching library resources for scientific journals.

4. Find the tricks that help you get results

Unlike in a Google search, typing in full sentences will not bring you satisfactory results. There are different methods to search different databases. Ask your librarian or do an internet search on how to best search your particular database. Check out Northeastern's Libguide on this.

5. Slowly expand your search to get additional results

A specific search might not return as many results. This can be good because these results will most likely be current and applicable. If you do not get enough results, however, slowly start expanding the date range, type of journal, or keywords to get more results when searching through publications.

From there you'll be able to find a wide variety of related technical reports, books, academic journals, and other potential results you can use for reference.

6. Use the pro features of the database

Academic search engines and databases are getting smart! In the age of big data and text mining, many databases crunch millions of scientific papers to extract connections between them. Watch out for things like:

  • related relevant articles
  • similar academic resources
  • list of "cited by" or "citations"
  • list of references

They all will lead you to other highly relevant scholarly literature!

7. If needed, you can move to another or more general database

When you have thoroughly finished searching a comprehensive database, you can move on to another to find more results as references for articles. Some databases that cover the same topics might give you the same search results, but they might also cover an entire range of different journals or online resources.

You might prefer the search system of one database over the other based on the results you get from keyword searches. One database might have more advanced search options than the other. You can also move to a more general database like:

8. Notice the big players in your field

There are experts in every field, people who have published a lot of scholarly content on your topic, people who get quoted or interviewed a lot and seem to be present almost everywhere when researching your particular topic. Pay attention to those names when searching a database and once you found someone interesting, you can search for more from that person.
