When using works (e.g. journal article, e-book) obtained from academic research databases or platforms, APA style rules are:
Material without page numbers
Web citations require much of the same information as print sources, but also provide the location of an online source:
1. Permanent identifier, etc. DOI, URN, Handle, or permalink.
Search for DOI:
2. Reference to web archive, Internet Archive or Memento, either existing version or version archived by you.
3. Avoid using the URL.
