About Citation Management Tools

Reference management software allows you store, organize, and format citations in all the styles described on this guide and many more. Many include features such as allowing users to tag or annotate citations, attach full-text PDFs to citations, create collaborative bibliographies, and create in-text citations. The four most commonly used reference management tools at the University of Delaware are described briefly below. For more information, please visit the Citation Management Tools guide.


The University of Delaware Library subscribes to RefWorks. All UD faculty, staff, and students can open one or multiple RefWorks accounts. This flexibility allows users to create accounts to be used by classes or research teams who need to share a collection of references. For more information, visit the RefWorks guide or contact Dianna McKellar.

EndNote Online

EndNote Online, the basic version of EndNote, is available to UD affiliates through the Web of Science database. Like RefWorks, EndNote Online is a sophisticated citation tool and offers a large number of citation formats and options, though the basic web-based version offered here has fewer features than the full desktop version. For more information, visit the EndNote Online guide or contact William Simpson.  


Zotero is a free, easy-to-use, open source citation manager available on the web. Many users like Zotero because of its simple integration into the browser and its ability to add PDFs, images, audio and video files, and snapshops of web pages with a single click. For more information, visit the Zotero guide or contact Kaitlyn Tanis.


Mendeley is also free on the web. The social networking capabilities are a major attraction of this citation management software. For more information, visit the Mendeley guide or contact Sarah Katz.
