Over a period of time, I have collected hundreds of ebooks and they are lying there on my hard drive.
Now I want use Calibre to configure *automatically* all those books so that I can manage my ebooks easily.

I have ebooks on my hard drive in various formats like .chm, .pdf and also some in audio format like .mp3.
ebooks name can include anything like combination of isbn, publisher, ebook name etc. and ebooks does not have proper format in their file names.

Now the problem is, I have to load each and every ebook manually into Calibre and then specify the isbn manually in Calibre and then ask Calibre to fetch other metadata for the ebook. If I have to do this for each and every book on my hard drive then it is very painful process and so I want avoid this process and want Calibre to automatically download all the metadata as soon as I load an ebook from my hard drive into Calibre. How can I do this ?

Also, how do configure mp3 files in Calibre so that managing/searching them is easy ?

Can you please clarify.
