Secondary sources can be reliable, but it is a best practice of scholarly writing to investigate for yourself if you can.
See here and here for more information on primary and secondary sources.
Let’s look at each of these aspects in more detail.
Reliable Sources A reliable source is one you can trust.
Italics and quotes are not needed in listing the name.
For instance, if your article is on Brian Miles, the start of your citation will be Brian Miles. It is essential to indicate the date of publication of an online source or the time it was modified.
Evaluate each source on its own merits for reliability when determining whether to cite it in a paper.
Primary Sources A primary source presents information gathered firsthand, such as the results of an experiment or data from a survey.
If the date is unavailable, use “n.d.” in parenthesis just after the title.
Write this by italicizing the word “Wikipedia.” followed by a full stop.
