In all the academic work, it is necessary to cite the sources that are not original. Otherwise, the work can be constituted in plagiarism, which is academically unethical and can even lead to cancellation of the work. Even incorrect citation is counted in plagiarizing the text that can make the students lose their grades.
Another important point of citing sources is to classify the statements as highly authentic and inculcate the weightage of supported evidence. Though the task of the bibliography is quite complicated, it is also the accurate way to upgrade the quality of your work performance. You may either do it manually or use an APA citation generator for accurate citations.
