Princeton has several online resources for style guides and citing sources available at the Citing Sources page These include:
8th ed. Style Manual Committee, Council of Science Editors. Chicago: University of Chicago Press, 2014. (In print at Firestone Ready Reference T11 .S386 2014.)
The Chicago Manual of Style is available online. This reference book is normally tethered to the reference section of the library but it can be now consulted online at any time.
Bibliographic managers can help with this task. The most common products (supported by Princeton) are Zotero, EndNote, Mendeley and RefWorks.
The library offers workshops for those interested to learn how to use Zotero, RefWorks or EndNote. Check the schedule to register for a session.
LaTex Users: All bibliographic managers will export your references as a .bib file, however Mendeley includes additional LaTex integrations.
