Conducting a thorough literature review is a foundational step in writing a research paper. However, access to scholarly databases and journals can be limited due to subscription costs, especially for independent researchers or students without institutional access. Fortunately, there are several strategies to overcome these limitations.

Start by using open-access databases such as Google Scholar, DOAJ, or PubMed Central. These platforms offer peer-reviewed articles freely available to the public. Many authors also upload preprints of their research on repositories like arXiv or SSRN, which can be cited if used correctly.

Another effective approach is using tools like ResearchGate, where you can request full-text versions directly from authors. University library websites sometimes grant limited guest access to certain resources, and browser extensions like Unpaywall can help locate free versions of paywalled articles.

For students balancing academic needs and financial constraints, turning to an affordable research paper writing service may offer additional support in organizing literature reviews or understanding formatting standards, while staying within budget.
