Zotero can be used solely as a web-based library but more functionalities are available with the downloadable desktop tool (Mac, Windows, and Linux). You can use both the web library and desktop library, as they'll sync up.
The Zotero Connector is a browser plug-in (Firefox, Chrome, or Safari) that allows you to save whatever you come across online into your web/desktop library.
ZoteroBib is a free web-based citation tool that generates citations from URL metadata, and saves what you enter to create a bibliography. It's free!
Zotero's basic File Storage plan (300mb of storage) is free, but there is a charge for more storage:
Part of a group using Zotero? "Group file storage always draws from the storage account of the group owner" (Zotero File Storage).
As open-source software, Zotero allows its users to create fixes and tools to improve the usability and function of the citation manager.
Citation styles are written in the XML-based Citation Style Language (CSL). Citation management tools all come preset with many of the major styles (APA, MLA, Chicago, AMA, etc.) but Zotero can also import new CSL files to format your citations in the style of whatever journal or publisher with whom you might be working. Find the style you need in one of the libraries below, download the CSL file, and then import it into Zotero by going to the Preferences menu (under the Gear icon in the plug-in), then to the Cite tab, and then Styles (see the image). You can add the style you downloaded by clicking on the + button. It will then appear in the citation style options when you export your items as a bibliography.
You can connect Zotero to the Library's OpenURL resolver so that citations can be searched for in the Library's collections through the Library Lookup tool.
Go to Preferences in Zotero Desktop, and under the Advanced tab, look for and select the resolver labeled "Stevens Institute of Technology" or enter the URL listed there (see image).
