Although there is a free online version of Endnote, this guide mostly refers to the desktop version that must be purchased. UofA students and faculty can get a discounted price at ualberta.onthehub.com.
PROS: Ability to store a large number of references and pdfs (10,000+); partially automated retrieval of full text (30-50% will be retrieved); deduplicates large numbers of references; increased citation accuracy due to large number of reference types; highly customizable; ability to work offline.
CONS: Price (~$140); license tied to one device; steeper learning curve than other options; importing non-traditional types of reference (e.g., webpages) can be challenging.
