Research and study tools covers software that helps you gather sources, take notes, and organise a project. Listings include reference managers, citation helpers, collaborative whiteboards, encyclopedias, and search tools for papers and data. The formats they import and export matter, along with the citation styles they support and whether they keep your library in a format you can move later. A tool can speed up the work, but it does not judge whether a source is sound, so the reading is still yours. Some entries serve one discipline and others work across fields.
