I'll qualify this a little: some of my PDFs do show an Author in Kindle's item list, but most don't, even though they do have Author metadata. And for those that do, I can't figure out where Kindle is reading the Author string from. And I cannot create a PDF of my own that shows Author when put on the Kindle.
Calibre reads the PDF metadata when importing PDF to populating its own metadata, but it doesn't seem to write any changes you make back to the PDF (unlike, say, ePub or mobi). Nevertheless, the PDFs that showed an Author on Kindle before being imported to calibre no longer show one when using the copy stored in calibre's library.
This has been driving me a little nuts this morning. Seems there are bugs everywhere I look.
... and if you highlight a PDF in the item list and click Right, you can see Title, Author, Filename in the summary/item options screen or whatever it is called.
Ok, I finally figured something out: if you want Kindle to recognize new PDF metadata, you have to remove it from any Collections it is in, or rename the file. Otherwise I guess the metadata is cached somewhere and doesn't get refreshed properly. One bug for Amazon.
Still it looks like calibre is not preserving or updating existing PDF metadata when you change some of calibre's. I have to go in and edit PDF metadata directly (with Acrobat etc.) after calibre is done doing its thing. One bug for calibre.
In any case, I guess I have a workaround now.
I spoke too soon: still can't get Kindle to display metadata in one of my PDFs...sigh.
