In many research settings, bibliographies are a central resource for collecting information about related work, keeping track of the own research record, and annotating this information with remarks. By its very nature, this information should be shared between researchers within a research group and maybe in larger organizational units (for example research institutes) as well. However, most tools used for managing bibliographic data do not support collaboration. Using ShaRef, users can share bibliographic information, collaborate, and publish and export data using a variety of output channels. ShaRef's goal is to make sharing of and collaboration with bibliographic information easier than it is today.
