You? Natural contrariness? Who would believe
that?!?
Taking Tolkien's Middle Earth canon as an example,
Nobody in his or her right mind, having read the entire canon (with or without the History of Middle Earth books, which really form a separate canon), would advise a first-time Tolkien reader to start with
The Silmarillion (much less
Unfinished Tales!)
, unless the individual giving the advice is either as sadistic as Major Helek in James Swallow's
The Dark Veil, or is actively seeking to turn the new reader
off of Tolkien. The sensible first-time approach is of course to start with
The Hobbit, then
LotR, then
The Silmarillion, then
Unfinished Tales.
And you hopefully get a copy of Robert Foster's Complete Guide to Middle Earth as a handy reference to avoid getting lost in
The Silmarillion and
Unfinished Tales. (It can also be helpful with
LotR.)
But once you've gotten through the entire canon in publication order, then (to me at least) it makes much more sense, and gives a much richer experience, if you read
The Silmarillion first, then
The Hobbit, and finally
LotR, inserting the various stories and fragments in
Unfinished Tales where they fall in the chronology.
Or with ADF's HC canon as an example, you could start almost anywhere, as a first time reader, since everything ADF writes is reader-friendly. But to me, it makes the most sense for a first-time reader to start with
The Tar-Aiym Krang, then either the rest of the first four Flinx books, or the
Icerigger trilogy, and then the rest in more-or-less in publication order. But once you've gotten through everything once, then (again, to me; YMMV) it makes more sense to start with
Nor Crystal Tears, and then proceed in order of internal chronology.
Of course, there are a lot of literary canons in which publication order
is internal chronological order. Baum's Oz, for example. And Madeleine L'Engle's "Murry/O'Keefe" canon. And Doyle's Holmes (even in the cases where a piece is said to have occurred some time ago, but "could not be released at the time," for some in-universe reason, the publication order matches
an in-universe chronology, if not the chronology of the in-universe events)
