II. Secondary source: this type of source relies solely on the primary source for its information and as such it comprises of second-hand information provided by other authors or researchers.
A reliable source is an information source that is unbiased, trustworthy and reliable. Also, a reliable source is typically backed up by evidence from various information channels and should be accurate.
In order to validate a reliable source, it is necessary that the information provided is checked against other credible sources to verify its accuracy.
This simply means that, if you got an information (data) from any source such as newspaper, website, television, books, radio or anywhere else, you should confirm the credibility and reliability of these information by verifying from one or more sources listed in the reference.
Hence, a reliable textbook should contain references to both primary and secondary sources.
Additionally, references are citations or links to all of the sources from which an author, writer, or researcher got his or her information from. One important thing that references show a reader is that the information is well researched.
