Artscroll released the Czuker edition Mikraos Gedolos Chumash that included most of the Rashbam's commentary but left out certain portions from the Rosin edition of the Rashbam. Artscroll explained that they left out portions whose authenticity they questioned for various reasons. If Artscroll continues printing the Mikraos Gedolos in this fashion, future scholars will have no idea that portions of the Rashbam were taken out. It is important that future scholars have access to the full unadulterated text and therefore Artscroll should acknowledge this error and reinsert that which has been removed in future editions.
