Scientific meetings are increasingly becoming dominated by published or soon to be published data (e.g. manuscripts that are accepted). Many scientists are wary of sharing earlier stage work, even if they have a manuscript in hand, since they have no idea how long it might take to get published. Meeting presentations and posters are generally not citable and only a limited number of individuals have access to the talk/poster, making it difficult to use these formats to establish priority. In contrast, a preprint is a public, globally-accessible document and is citable. Thus, if a scientist wishes to disclose new data at a scientific meeting, they have the option of also reporting that data either before or after the meeting in the form of a preprint. In contrast, if the presented work is only submitted to a journal, the time until public disclosure is not certain.
