Hallo!
sorry for my english, german goes better

I use Calibre since 6 years, but only for transfer between PC and reader.
I find a good book about Calibre in german - Reibold, Holger: EPUB kompakt.
I find new functions and wiil use it:
1) metadata from ISBNdb.com - he works, but the same autorname coming in different versions "Weber, David" or "David Weber" - i will it in the first form. Which configuration must i use?
2) i have books from different sources, with different rules of filename, i will use "{author_sort[0]}/{authors} - {series} {series_index:0>3s} - {title}" by save to drive, but i become no new directory with the first character of the autors name, and all files was written to the main directory
can somebody help?
