How do you organize drabbles?

[valiha]

and short stories in calibre? Do you merge all drabbles written by one author into one html, which is what I was thinking about, or keep them separate? Would you also merge all short stories into a sort of a Fanfiction Anthology for that particular author or fandom or whatever?

ETA I also need advice on how to title fics such as anon fills in kinkmemes, multiple fils of a single prompt, anon comment fics and what kind of regex to use in calibre's Preferences > Import/Export > Add books section in such cases, or would I need a different one for each occasion?

Right now I have

(?P<author>[^_-]+) -?\s*(?P<series>[^_0-9-]*)(?P<series_index>[0-9]*)\s*-\s*(?P<title>[^_].+) ?

which handles those with titles such as Author - Series # - Title.ext well; how would you go about saving fills from, say, norsekink, if you didn't want to save each fill separately?
