Welcome! This is a step-by-step guide designed to help you perform a literature review using library resources.
- Finding a topic and creating a search strategy -- identifying keywords and brainstorming for synonyms
- Locating relevant sources
- Use WorldCat UMD to find books, DVDs, government documents etc.
- Use Research Port to access databases for articles from magazines, newspapers and journals
Finding a Topic and Creating a Search Strategy
The first step in a literature review is to identify the main concepts in your research question. Once you have done this, you need to brainstorm for synonyms and related words. For example, you could use Terrapins but someone else might use the term Terps; in order to find all of the relevant results you will have to use both terms.
Boolean operators are used to connect keywords in a way that all search engines understand. The most commonly used ones are: AND and OR:
Using AND will make your search more specific / narrower. The results will only include items that use both of your keywords.
Using OR will make your search more inclusive / broader. By using OR the number of your search results will increase. It is useful to use OR when you are unsure which keyword would work best. The results may include one, two or all three of your keywords.
A search for Terps OR Terrapins will produce results that include either term, or both terms within the records retrieved.
Be careful combining AND and OR in the same search sentence as the search engine may not interpret your search the way you intend because of the order of operations (like in math class). Use parentheses to keep ORs together.
Example: Maryland AND (Terps OR Terrapins)
You may also choose to limit your search results by excluding certain terms. To do this, use NOT. For example, if you want articles exploring a certain audience or medium, but do not want to include editorials, you could search:
(audience AND television) NOT editorials.
Use the NOT connector sparingly, as you may eliminate some articles or information that could be useful. This connector can, however, be a helpful tool if you have a large number of items in your results list and you want to refine your search.
Truncation and wildcards are other ways to help you to locate additional information on a topic, and locating variant spellings of terms.
|Truncation (* Symbol)||
Wildcards (? symbol)
|Finds all forms of a word (most databases use the * symbol).||
Replace any single character, either inside the word or the
For example, entering econ* will search for
|For example, entering wom?n will search for
women and woman.
A note about keyword searching: Remember, if you search a database with a certain word or phrase and you don't retrieve results you feel are relevant, it doesn't mean that there are no other articles in that database on your topic. It may mean that you need to try other related words in your search, such as synonyms.
Helpful Hint: Use Your Findings to Locate Additional Research
One tactic to try in a literature review is to take a moment to review the list of notes, references or resources included in a source that you feel is particularly on-target for your review. In this way, you can start with a small list of resources, which can then "grow" via links to other relevant research. This can also be a means of locating key studies - so be on the lookout for "repeat" citations (articles/works cited by more than one study).
Another tactic to try is to search Worldcat UMD for published bibliographies on an author of note. To do this, enter the name of the author and add the word "bibliography."
As you are assembling your list of resources - consider entering them into a grid to see what common themes/ideas emerge. A source of a sample grid that can be used for this purpose is "How to Prepare a Source Grid: An Example Project" - although you are free to develop your own style for organizing/tracking your results.
