Human error? We have checked and rechecked the datasets used in this book. But the data we processed was more than 10X what was finally used. There is always a chance that Sod’s Law crept in somewhere. In case you spot an error, please let us know at the email ID above. We will gratefully acknowledge your help. In the process of updating, we will continue to recheck data on our own too.

Is it free? For now, yes—this data companion is completely free to access. If you’re a student or teacher, it’ll always be free. If we ever add a nominal fee later to support ongoing updates, we’ll be transparent—and generous.
