There are many very unique types of resources that can be challenging to cite. How do you cite government publications? How about a web page? The list could be seemingly endless: standards, patents, technical reports, datasets. Most of the citations styles included in this guide (APA, MLA, Turabian, Chicago Manual of Style) have sections on how to cite typical sources - but not the more unusual ones.
Many of our library guides have a specific section of the guide devoted to citing specific types of documents - e.g., how to cite a patent. We have compiled some of them here for your convenience.
