It discusses conceptual (theoretical) literature and data-based (research) reports as the two main types of sources. Conceptual literature includes theories, models, and frameworks, while data-based reports consist of published qualitative and quantitative studies. Both primary sources, from the original authors, and secondary sources, which discuss or summarize other works, are important. The document also lists several prominent nursing and health-related journals that frequently publish nursing research reports.
