Nautilus Columns is a Nautilus extension that adds music (mp3, WAV and FLAC) and EXIF metadata info to the Nautilus List View.
A new version of Nautilus Columns which adds PDF info (thanks to draxus) is available in the WebUpd8 PPA. This is very useful for those who have a lot of PDF files for which the title is not descriptive.
To display the PDF info, in Nautilus go to Edit > Preferences > List Columns and check "Artist" (Artist was used instead of Author to keep the Nautilus columns number low) and "Title", then navigate to a folder where you have some PDF files and change the Nautilus view to "List View". Please note that your PDF files need to have the author and title info available or else you'll get "n/a" in those fields.
