Think about what it took to print something back in 91. Computers weren’t widely used in offices for regular typing. That pamphlet had to be gone over a hundred times before it went to the print shop.

A promotional booklet intended for a few commercial users may not have been gone over as carefully as something intended for a wider public.

One more thing. The reason an author is asked to review their own bio material prior to publication is very simple. It's cheaper and less embarrassing to correct errors prior to paying for a booklet or anything else to be published than to make the corrections afterward. This was not a rank amateur lit agency. They knew the drill. Of course they asked Obama to review the final copy. To suggest otherwise is grasping at straws.
