You may need to open a free account in order to view or download files on OneDrive.
The OneDrive files can be searched. The “Search everything” box at the top will initially bring up files with the search phrase in the title. “Show more results” looks through the contents of the text files.
For example, if you search for “golden ratio” you can find all text files with this phrase somewhere in the text.
Search for ‘pbk’ and you will see the pdf books.
Search for ‘{oo}’ and you will find transcripts of audio files, or text files that have been run through text-to-speech software.
