Zotero is designed to easily manage references in numerous formats including books, documents, journal articles, magazine articles, manuscripts, newspaper articles, web pages, and many more. You can create collections of references for different projects and add notes, tags, and relationships to other references in your Zotero library. You can add files, or links to files, to make it easy to locate PDFs of articles, and you can capture web pages so ephemeral web information is still accessible.
Numerous library catalogs, databases, and websites allow Zotero to populate the bibliographic data fields with just a click—no more typing! Well, almost. Not all sites talk to Zotero, but you can copy and paste information into the item records, or just type in the ISBN and the record is completed with the data from the Library of Congress catalog.
Zotero is free plugin for Firefox, Chrome, and Safari browsers on Windows, Mac, and Linux computer platforms. Plugins for Microsoft Word and LibreOffice make it easy to add correctly formatted endnotes to papers with a number of supported citation styles. You can download the Regional History Series style, based on Turabian, and add it to Zotero to better ensure your citations are correctly formatted for RHS publications.
