Time for action – editing PDF metadata

We shall add PDF metadata to our book of equations. Besides choosing sensible keywords, we will set the title and the author's name. During development, why not choose the great mathematician to whom we dedicated our book. So, let's do it!

1. Open the file preamble.tex and add the following lines:

   \hypersetup{pdfauthor={Carl Friedrich Gauss},
     pdftitle={The Big Book of Equations},
     pdfsubject={Solving Equations and Equation Systems},
     pdfkeywords={equations,mathematics}}

2. Save that file. Go to the main document equations.tex and Typeset. Let's inspect the document properties! So, if you use the Acrobat Reader, click on the File menu and then Properties:

   

What just happened?

The most commonly used meta-information options are:
