Powerful reference management software can consist of a database to enter and generate full bibliographic references. They integrate with word processors to reduce errors and provide citation creation and reference management features. Data can be exported and imported between EndNote, Mendeley, and Zotero using specific file formats and attention to duplicate references. Reference management programs differ in available resources, import filters, citation styles, operating systems, mobile apps, online storage limits, and import/export capabilities. Each has strengths like collaboration, cost, or platform independence, but also weaknesses such as usability, file sharing options, or lack of database search tools.
