Here is a new user of Calibre,

I am trying out Calibre and Alfa Ebooks Manager if either can be used for my ebooks collection. For trial, I chose 5 random books and imported in both the programs.
Alfa Ebooks manager imported metadata for all 5 ebooks flawlessly from Barnes & Noble (I chose this option over amazon and others) but Calibre could not import metadata for any of them.
How does this metadata import function really work? In the demo video, Kovid only mentions that it downloads from the internet but where does it actually download from? Can you change this search option?

I checked through forums and wiki too but did not find any answer.

Any help is appreciated.

Thanks in advance
