There are several approaches and strategies to employ when doing online research using the Library of Congress website. Starting with the single search box, found on the Library of Congress website, you will discover digital primary sources as well as research tools and guides created by librarians. Use the tabs below to learn more about how to search the Library's website, expand your search to include databases and online catalogs, and evaluate the results of your research.
Knowing where and what to search are just as important as understanding how to search; deciding where to start may depend on the topic you are investigating and on the kind of information you are looking for. Are you looking for historical newspapers, directories, journal articles... the answers to these questions will inform where you search.
The keyword you select for your search should describe important aspects of your investigation, therefore, selecting the appropriate keyword(s) for your search is the foundation for your research. Despite their various algorithms and filters, databases, search engines, indexes, and even catalogs work by matching your keywords to their records, this is how you get search results. The more keywords these search tools can find, the more relevant the results will be for your search. The search will only give you back what you tell it you are looking for, so selecting those keywords and related or synonymous terms, is important. For example, if you are researching teenagers and their reading habits, you want to make sure your keywords include — teen, teens, teenager, youth, young adults, and depending on the page you want to target, even — child, children, kids, etc.
Deciding on a topic you'd like to write about and defining the parameters of your research is one of the most challenging and important aspects of the research process.
When deciding upon a topic, remember these three rules:
Try browsing through these resources to help you develop some ideas:
You can search by typing a keyword into the search box, and you can also search for a specific type of item—e.g., map, audio recording, or manuscript (handwritten document)
There are a number of ways to view your search results (e.g., list view, gallery view, grid view etc.). It is also possible to sort, or re-sort, your search results by date or title. You can also narrow your search results using filters for year, subject, language, and more.
On LOC.gov, each item generally has a record that includes details like title, date created, creator, and more. There are also clickable details that link to similar items and related materials that can help expand your research. On this page, you can also learn about copyright restrictions related to the item. If you have questions about copyright, check out the section in this guide on “Citations and Formatting.”
The Library of Congress Online Catalog is available at https://catalog.loc.gov/. It is the primary search tool for discovering all types of materials in the Library's print and online collections. Search results will provide full bibliographic information for each collection item along with the location and call number needed to request and use that item at the Library. If the material is digitized, there will be a link to the primary source online.
There are several ways to search the online catalog. The instructions below focus on the Advanced Search option.
Developing a search strategy can help to narrow down your results lists and replicate a consistent search across multiple e-resources/databases.
Throughout the process of conducting your research, you will find yourself pausing to reflect, evaluate, and refine your results and research.
You may need to repeat this process across a number of collections, subject areas, catalogs, and/or databases in order to get the exact type of results you are looking for.
Remember, when using the Internet for research, it's important to evaluate the accuracy and authority of the information you find on websites. Search engines, like Google, find sites and pages of all levels of quality. Try to keep these things in mind when deciding if a web page is reliable and appropriate for your research:
