Citation management software, also known as bibliographic management tools, are web-based citation tools that gather, organize, and store your research as well as generate citations. You can create formatted reference lists in a variety of publishing styles. The most popular citation managers are Zotero and EndNote, which offer freemium memberships (free basic membership levels up to paid subscription levels).
Most of the library catalog records and databases allow you to directly add references to your citation manager libraries. You are also able to save files directly from most internet pages.
