Evaluate the sources of reference materials to determine their credibility. It is important to use only reliable sources in seminar papers, otherwise you will damage your reputation as an author. Using the library database will also help to ensure that your papers have a large number of trustworthy sources. In order to determine whether the source is trustworthy, you need to consider the following points:

Author Certificate Select a source that contains the author's name and provides credentials for the author. These certificates should explain why this person is qualified to express his opinion on this issue. For example, if the author is a doctor, an article about medical conditions will be more trustworthy. If you find that a source does not list the author or the author has no credentials, the source may not be trusted.

Citation ponders whether the author has fully studied this topic. View the author's bibliography or cited works page. If the author provides little or no information, then this source may be unreliable.

Has the author put forward an objective and reasonable explanation for this topic? Does this tone often indicate that people are strongly inclined to one side's argument? Does the argument often ignore or ignore the concerns or valid arguments of the opposition? If these appear frequently in the source code, it may not be a good choice.

The publication date depends on whether this source provides the latest information on this subject. It is worth noting that the publication date is particularly important for scientific disciplines, because new technologies and techniques make some early discoveries irrelevant.

Information provided by the author of the paper If you are still questioning the credibility of this source, please cross-check some information provided against reliable sources. If the information provided by this author contradicts one of your reliable sources, then it may not be a good source for your paper.
