Notebook Document Processing

Since Version 3, notebooks have been saved as symbolic expressions that can easily be loaded and processed into the Wolfram Language, but doing so requires a significant understanding of the notebook's symbolic representation. NotebookImport clears that hurdle by making it simple to pull text, graphics, and code from notebooks.

Import all "Notes"-styled cells found in the documentation for Cos, convert them to plain text strings, and return them in a nicely formatted table.
