Greetings! I'm filling out a smallish personal library for the first time, and along the way I discovered that a couple of my ebooks had updated revisions, so I re-downloaded them. Which is fairly common - technical errata can lead to a minor rewrite, or spelling/grammar corrections, etc.
Personally I'd like to keep
all of these versions. Ideally as the "same" book, because they really are - often they don't even have a new ISBN. Partly so I can hang onto them and e.g. compare in the future, and partly because... well why not. Disk space is cheap, and ebooks are
tiny.
I'd also very (very!) likely end up using something like this to keep variants of epubs for specific devices, as style/etc support is most definitely not consistent. Again, it's "the same book", but the details matter enough to be worth keeping multiple varieties around.
The UI / prompts / manual all seem to assume that I want to *get rid* of duplicates though. Merging books will let me blend the metadata, but it's somewhat ambiguous about what epub file will be retained. I can edit the metadata and + to "add" a new format to a book... but that replaces the existing one if it's a format that already exists. While this is obviously useful while importing a bunch of possibly-duplicate data, it seems like it might be preventing what I want.
Is there a way around this? Can I keep multiple epubs in a single book?
One (e.g. the most "advanced" contents, either by technical capabilities or the newest content) will always be "preferred" for automatic conversions and reading in calibre and whatnot, but I'd prefer not to either lose or visually-duplicate the other ones.
I haven't been able to conjure up a Google search, nor find it in the manual or UI, so I'm hoping the forum knows a trick or two
