This program is designed for the management of large collections of books, papers and other publications (good enough at least up to ~ 10k of records), mainly for science-oriented writing and collaborative work between small groups of researchers. Our development team was inspired by other prominent tools like JabRef or Mendeley and has been focused on a lightweight, self-sufficient tool, which can be combined with other technologies. BraStBook uses SQLite format to store data, Qt GUI to be cross-platform and can be combined with cloud storage like DropBox/Google Drive and Git repositories for syncing between computers and accounts of different people.
