Citing the work that supports your research is both an ethical issue and a legal issue.
Which reference system to use depends on your subject and your teacher, so be sure to ask at your department for the appropriate reference system.
The ethics of citing is based on the scholarly tradition of giving credit for information and ideas that are not one's own. Science has a long tradition of acknowledging priority through citations. You have the ethical responsibility to cite all works that were used to support your research, to give credit to earlier work and to provide a clear path for those who follow in your footsteps.
Reference management programs will save you time when you cite and when you create your bibliography. You can quickly save articles and read them later. Are you interested to use a reference management program? Learn more in the Reference management guide.
