EndNote Basic is the free version of one of the most popular citation managers (EndNote). EndNote Basic is a web-based citation manager that helps you locate, organize and store bibliographic data. Think of EndNote Basic as an online filing cabinet with amazing search functions. EndNote Basic integrates with Microsoft Office Word (and potentially other word processing systems) to assist you, while you are writing research papers, manuscripts and grant proposals, in inserting in-text citations and generating the resulting reference lists. Your EndNote Basic database can be organized into "Groups" (think of them as folders) and there are robust sharing and social networking capabilities.
EndNote Basic allows you to store up to 50,000 references online and store PDFs (up to 2 GB). If you need more storage space or want to access additional capabilities, more capacity is available with a personal subscription.
EndNote has many excellent tutorials and guides available on at the EndNote Training webpage (http://endnote.com/training). Although there are not training materials specifically for EndNote Basic, the functions that are detailed on these tutorials will apply to EndNote Basic -- you just may not have access to all of the functions (the Basic version has more limited functionality than do the subscription-based versions).
If you are interested in really learning how to make use of the robust citation management features of EndNote, spend some time with these detailed tutorials and guides so that you can become aware of all the ways in which EndNote Basic can assist with making your research continuum more efficient -- a process that starts with your initial research and concludes with citation formatting within your final research projects.
