I'm a librarian who loves anime, manga, and reading a wide variety of genres.
PSA: e/em/eir in Provenance are NOT TYPOS. Please do not lobby Amazon to remove the book until it is "fixed." Thank you.

Although I experienced a bit of confusion the first time I came across an instance of "e" (it was capitalized and I thought it might be the person's name), it wasn't that hard to figure out. It never occurred to me that people might report it to Amazon as typos. O_O
