Serps Title for pdfs

Where does it come from?

What does Google use for the serps title for pdfs?

I've put some lab handouts on my Web site, as PDF files that were generated by Microsoft Word from Word documents. Google uses as the title, the text that was formatted with Word's "Heading 1" style. I don't know what this means in terms of the PDF file itself, though.

I don't quite know the parameters, but I do know that I often see results with "EWSLETTER" as the title, with the larger drop-cap N ignored.

PDF files have "Meta Data", which is specifically intended to be used by robots / 3rd parties to see extended information about a the file which cannot be seen "in" the pdf files itself. - images can also have this meta data.... Google uses this data on the serps.

I just realized that the PDF isn't generated by Word, but by Mac OS X. It's an option in the standard print dialog in all applications.

I took a look at the "Document Properties" in Adobe Reader. The title, subject, author and keywords fields are all blank. So Google isn't getting the title from any of those, at least in my case.

As I mentioned before, the title is formatted in the "Heading 1" style. It's also the very first "paragraph" in the document. I don't know which is more important.
