They'll be either Adobe PDF or EPUB (I have a Sony Pocket Edition).
I have just repeated with an import of 2 x new Adobe PDF books and the author name is picked up correctly (on the older version of Calibre).
The only difference I can find is that in Preferences, Add/Save - on the older version of Calibre, nothing is ticked. On the newer version on the other machine, Read Metadata only from File Name is ticked.
I'll test the other machine later with these same two files and with that box unticked to see what happens.
