I just imported 180 or so Doc Savage books from Blackmask, using the "Add books from directories, including sub-directories" option of Calibre. Did a fine job, but the title could only be grabbed from the filename. I deleted them, then wrote a bash script to rename all the files from the folder names (which had the full titles) and re-imported. Then a bulk metadata edit took care of most of the rest.
So, not terrible. And these books don't have the best choices of metadata or particularly stringent values eg:
<TITLE>THE MAN OF BRONZE</TITLE>
<META NAME="Author" CONTENT="A Doc Savage Adventure by Kenneth Robeson">
<META NAME="Description" CONTENT="Mystery, Suspense, History, Gothic, Literature, Books, Arts">
and the original filename was manbronze.htm
. Still, it might be useful, especially in the future as things might get better tagged -- if apps support it.
Sort of a chicken-and-egg thing.
