> "Classification of Spreadsheet Errors"

It's a taxonomy of the types of bugs spreadsheets have.

There are these for most other programming languages too.

Look, my first job was translating an Excel spreadsheet into an actual application and we found errors all the time.

It doesn't mean that it is useless.
