Here's why:
* Redundant information: The database name and retrieval instructions are usually implied by the DOI (Digital Object Identifier). If a DOI is available, it's the preferred way to identify the article.
* Accessibility: The retrieval instructions may not be applicable to all readers. For example, someone may not have access to the same database you do.
* Consistency: Keeping references clean and concise makes it easier to read and understand.
What to include in an APA reference:
* Author(s): Last name, first initial. (If more than 7 authors, include the first six and then "et al.")
* Year of publication:
* Article title: Capitalize only the first word and proper nouns.
* Journal title: Italicize the journal title.
* Volume number: (Issue number)
* Page numbers:
* DOI: (if available)
Example:
Smith, J. A., & Jones, B. (2023). The impact of social media on mental health. *Journal of Social Psychology*, 103(2), 123-145. https://doi.org/10.1037/xxx
If a DOI is not available:
You can provide the database name and the article's unique identifier (e.g., article number, accession number) within the reference. However, this information is less preferred than a DOI.
Example:
Brown, C. D., & Green, E. F. (2022). The role of technology in education. *Educational Technology Research*, 15(3), 45-60. Retrieved from http://search.ebscohost.com/login.aspx?direct=true&db=eric&AN=ED598234
Important: If you have specific instructions from your professor or publisher, always follow their guidelines.
