Civil law, or civilian law, is a legal system originating in Continental Europe and adopted in much of the world. The civil law system is intellectualized within the framework of Roman law, and with core principles codified into a referable system, which serves as the primary source of law. The civil law system is often contrasted with the common law system, which originated in medieval England, whose intellectual framework historically came from unmodified judge-made case law, and gives precedential authority to prior court decisions. Historically, a civil law is the group of legal ideas and systems ultimately derived from the Corpus Juris Civilis, but heavily overlaid by Napoleonic, Germanic, canonical, feudal, and local practices, as well as doctrinal strains such as natural law, codification, and legal positivism. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
