This date is off by one year.

Bibliographic sources identify Matthew Ward's translation of The Stranger as first published in 1988 by Alfred A. Knopf. WorldCat lists the book as a 1988 print book: "Publisher: Alfred A. Knopf, New York, 1988." The Albert Camus Society likewise summarizes the work with "Translator: Stuart Gilbert (1946); Matthew Ward (1988); Sandra Smith (2012)."

The likely source of confusion is that Vintage International published a paperback edition in 1989. Penguin Random House's page for the Vintage edition says "Paperback ... Published on Mar 13, 1989," and Open Library lists that Vintage International edition as 1989 while noting it is a translation by Matthew Ward.

So the translation year in the infobox should be 1988, with 1989 applying only to the later Vintage paperback release.

This sentence misidentifies the publisher and date of Matthew Ward's U.S. translation.

WorldCat records the 1988 U.S. publication of Ward's translation as: "Publisher: Alfred A. Knopf, New York, 1988." A separate WorldCat record for the Vintage issue identifies it as "1st Vintage International edition" published in 1989.

Penguin Random House's current page for the Vintage edition confirms that it is the paperback release and gives the publication date as March 13, 1989. Open Library likewise lists the Vintage International edition as 1989 and marks its copyright date as 1988, which helps explain how the error may have arisen.

So the accurate sequence is: Knopf published Ward's translation in 1988; Vintage published its paperback edition in 1989.
