A literature search is where students comprehensively explore published literature in order to find scholarly articles on a certain topic. Literature searches are fundamental when it comes to research and academia. Suppose you are a student, a researcher, or a professional. In that case, you may have to conduct a literature search in your academic life. Therfore, in this guide, we will tell you how to perform a literature search step by step.
How To Conduct a Literature Search?
1. Define Your Research Question
Your research question is where you create a clear, focused, and answerable query that guides your study. You can start defining it by identifying a broad topic you’re interested in. Then, you can narrow it down to a specific aspect that intrigues you.
Think about what you want to discover or understand better about this aspect. After that, formulate this into a question that is neither too broad (hard to answer comprehensively) nor too narrow (limited information available). Ensure it’s specific and researchable, meaning there’s enough existing literature to explore, and it’s possible to answer through research methods. A well-defined question sets a clear direction for your study.
2. Choose the Right Databases and Resources
The right databases and resources are essential for effective research. So, identify databases specific to your field. For literature search examples, you can utilize PubMed for medical research, JSTOR for humanities, and Scopus for a broad range. Academic search engines such as Google Scholar are also useful in order to search for scientific papers or scholarly literature.
If your topic is interdisciplinary, consider multiple databases covering different fields. University libraries offer access to various databases and journals. Don’t overlook specialized research institute databases for niche topics. Remember, the choice of database can significantly influence the quality and relevance of the information you gather, so choose wisely based on your research topic and discipline.
3. Develop a Search Strategy
A literature search strategy involves carefully selecting keywords and phrases related to your research question. Break down your question into main concepts. Then, list synonyms or related terms for each concept. Use Boolean operators such as AND, OR, NOT to combine these terms effectively: AND to narrow the search, OR to broaden it, and NOT to exclude irrelevant results.
Consider using truncation symbols to include various word endings and plurals. It’s also helpful to use phrase searching with quotes for specific phrases. Start with a broad search, then refine it based on initial results. This strategy ensures a comprehensive and focused search, capturing relevant literature.
4. Use Advanced Search Techniques
Advanced search techniques can refine and improve your research results. Phrase searching, where you enclose exact phrases in quotes, ensures you find specific terms together. Utilizing Boolean operators (AND, OR, NOT) helps to combine or exclude keywords effectively. Truncation symbols (like an asterisk *) allow you to search for multiple forms of a word, capturing more variations. Employing wildcards (like a question mark ?) can find different spellings. Also, explore subject headings or controlled vocabularies unique to your database for more precise results. These techniques collectively enhance the accuracy and efficiency of your literature search.
5. Conduct the Search and Review
Searching involves executing your search strategy in selected databases. After you initiate the search, review the results and pay attention to titles and abstracts. This initial screening helps assess the relevance of each article to your research question. Look for articles that directly relate to your topic and research objectives. You should adapt and refine your search terms based on the findings. As you review, you need to consider the sources’ quality, credibility, and recency. This process allows you to identify the most pertinent literature for your study. It lays the foundation for further investigation and analysis.
6. Obtain the Full Texts
Full texts are crucial for comprehensive research. Once you’ve identified relevant articles during your search, there are several ways to access their full texts. If you’re affiliated with a university or institution, you may have access through your library’s subscriptions. Many journals offer free access to researchers. To find full texts, you can also use platforms such as ResearchGate, Academia.edu, or preprint archives. Interlibrary loan services allow you to borrow materials from other libraries. Respecting copyright and fair use policies when obtaining and using full texts is essential. Having access to the complete articles ensures you can thoroughly evaluate and incorporate them into your research.
7. Organize and Evaluate Your Findings
Accurate and authentic findings are crucial for effective research. Use reference management software such as Zotero, EndNote, or Mendeley to organize and store your collected literature. Categorize and tag articles based on their relevance and themes. Critical evaluation is essential. So, assess the quality, credibility, and methodology of each source. Consider the author’s expertise, the publication’s reputation, and the recency of the research. Ensure that the selected literature aligns with your research question and objectives. If you organize and evaluate findings, it will streamline your work and also ensure that your research is based on credible and high-quality sources. This enhances the validity of your study.
8. Keep a Record of Your Search
You should keep a record of your search for transparency and reproducibility in research. Therefore, document your search strategy, including the databases used, search terms, and search date. It will serve as a reference point for future research and allow others to replicate your search process. It also helps you identify and avoid duplication in your search efforts. In addition, for systematic reviews and academic research, a detailed search log is required to demonstrate your study’s rigor and integrity. Overall, keeping a record of your search ensures that your study is well-documented and follows ethical and academic standards.
9. Follow Ethical Guidelines
Following ethical guidelines, respect copyright laws and fair use policies when using others’ work, including proper citation and attribution. You should obtain the necessary permissions for copyrighted materials, such as images or extensive excerpts. Adhere to ethical guidelines for human or animal research, obtaining informed consent and following ethical review processes. Maintain data integrity in order to ensure accurate and honest reporting of results. You can avoid plagiarism by properly citing sources and giving credit to original authors. Ethical conduct in research upholds the integrity and credibility of your work. It contributes positively to the academic and scientific community.
Literature Experts and Services
In some cases, you may require assistance with your literature search. This is where literature experts and scientific literature search services come into play. These experts can provide literature search and review services and valuable guidance to formulate search strategies, find elusive articles, and ensure that your search is comprehensive before journal selection and submission.
Conclusion
You must know how to perform a literature search if you are involved in research or academic pursuits. You can learn this skill by following the steps outlined in this guide. As a result, you can perform effective literature searches. It will contribute to your knowledge base and support your research endeavors in the future.
