A mention is a starting point, not a recommendation.

We have withdrawn the automated rankings previously shown on this page. Mention counts and extracted titles did not provide a reliable basis for recommending a resource.

What you can check now

Our resource page identifies the official author, publisher or provider, the task an option may suit, its access costs and its limitations. Free guidance and library options come before optional purchases.

We do not claim that community popularity proves effectiveness, that every book has been personally tested, or that a recommendation predicts what will help you.
