At this point, any documentation that is not directly from the source, is not trustworthy. Embellishment, forgery, erasures, additions, leaving pages and entries out, adding pages and entries, changing dates, etc - are wildly rampant.
Aside from the issue of the Colb, there are a number of examples. The letter from the U of HI - the author ASSUMES that the student who enrolled in Fall 1960, is the same person as Stanley Ann Dunham. There has been no transcript. The U of WA transcripts were apparently supplied, with a covering note, AS A SCAN SENT BY E-MAIL. (Or a FAX) There is no provenance. A later communication corrects a 'misunderstanding' about the date of commencement. The original report had the date as August 19, 1961. The explanation was that this was transcribed incorrectly and should have been SEPTEMBER 19. How-ever, the semester commenced September 25, according to the U of WA calendar from 1961. Small difference? Why can't they get ANYTHING right?
The U of WA transcripts include Mercer Island High School graduation in 1960. Funny that. Aside from some very suspicious images in which Stanley Ann Dunham appears to have been inserted, there's nothing. NOT A SINGLE YEAR BOOK. None of her 'classmates' can find their yearbooks, and when asked, someone at Mercer Island High School said -
We had SIX yearbooks until recently, BUT THEY WERE STOLEN.
