In a way, complaining about issues in a few resource seems ungrateful. On the other hand, I am investing an incredible amount of time trying to morph these resources into something usable in a daily classroom setting. So, after saving each individual section (120+) in a book, I go in and verify each Web link, fixing the ones that don’t work.
That is fine, as it were, for links that actually exist. When a link to an answer key goes nowhere, well then, that is another ball of wax. I guess I am left to hunt it down, assuming it actually exists somewhere or to write my own answer key. Sigh, this is why just buying textbooks is so much easier.
