After 100 years as a print publication, the Chicago Manual of Style has finally made it online. It will not be free, but I expect the UVM library will get a subscription.
In addition to the manual itself, the web site offers a Q&A section, some tools and tips, and a FREE citation quick guide that covers the most common reference types. The latter may be all most students need.
Of course, if you are using the bibliography program, EndNote, you don’t have to worry about any of that as EndNote will format your references and citations in Chicago Style with no fuss on your part. UVMers can get EndNote for free from our software site. Check the CTL events calendar for workshops on EndNote or see the Library’s EndNote support page for more information.
