The first feature that was implemented was the correct formatting of article citations according to different journal reference styles.

Reference management (RM) softwares, or reference managers, first appeared in the late 1990’s. in Chemistry and Physics) or alphabetically ordered (in Life Sciences), modifying one’s reference list would be painful. Depending on whether the journal was asking for references to be text-ordered (e.g. Until the early 1990’s, researchers had to enter literature manually when inserting literature citations in their manuscripts. Also, one has to handle multiple references, from multiple journals, and publishers, along the realization of their research and organizing all this together in a homogeneous manner, can be very nerve-racking. Before creating new data, researchers have to understand the existing data in their field, so that they can reach what they are pursuing in the best conditions possible, i.e., with the simplest route and the minimal cost. Hence, it is important to be aware of what is already known when starting out a project. One of the main qualities of research work is to bring out a new piece of knowledge. A good literature review is the building ground for carrying out an efficient and well-designed research project.
