This is a smart, lucid, and thorough lecture from Ian Johnston, a professor at Malaspina University-College in Canada.

Although he occasionally gets wrapped up in theoretical aspects (fortunately most theoretical terms have definitions in the text), his comments on looking at Solitude as an epic and the concept of time in the novel are particularly good. This is a helpful link if your own professor didn't give the best lecture on the book.
This link is practically a mini-ClassicNote in itself.

As part of a class at Hotchkiss Academy, the instructor put together a list of essay questions and extensive commentary on the style, structure, and techniques of Solitude. If you're just interested in essay topics, they're at the very top of the page. The rest of the page goes in-depth and includes a plot summary. There's also a very cute picture of Gabriel Garcia Marquez at the top.
This is a New York Times book review of One Hundred Years of Solitude from 1970,

when it first appeared in English, written by the beloved Harvard professor Robert Kiely. This link is excellent because it is a view into people's reaction to the book 30 years ago, before critical analysis made it a classic. A great idea if you're doing a paper on the impact of the book when it first came out.
