A book is typically identified by the title and the author. You have to use the actual title in the title field, and nothing but. Don't try to add anything extra to the title. The correct title can easily be found inside the book. Then calibre may be able to automatically fetch other metadata.

If you right click a book, and select edit metadata, then you can change the series information.

Read the manual for more information, and search for relevant threads here.

I suggest that you try to download some well known classic from here, and then check out the metadata. Most likely all the metadata will be set correctly. Then try save that book to disk. And try other things.
