Any reason it would be on file at Berkeley?
Assuming the reference is to UC-Berkeley, I don’t recall hearing he ever attended class there, perhaps he applied, but who sends a birth announcement with a college application?
Ok, I went to the linked site. I tend to avoid that since often those links do little more than give me pop ups or worse). So, some intrepid student at UC-Berkeley sought out the microfiche from 1961.
It’s not overly impressive in that it doesn’t provide the information everyone seems to be seeking nor does it address the ‘natural born’ issue.
Major university libraries have extensive microfilm newspaper libraries. I was doing some microfilm research at a university a while back, and the guy next to me was looking at Czech newspapers of the 1950s.
The presumption would be that the UC-Berkeley library has a collection of microfilms/microfiches of a number of out-of-town newspapers covering whatever dates they do, that the Honolulu Star Bulletin would happen to be one of them, and that the library's HSB holdings include the date of the announcement of Obama's birth.
There need not be any link of Obama to the UC-Berkeley campus.
But, though not implausible, I find that the library's permanent holding of the HSB is unlikely. Could it be that on request of the citizen-investigator, the UC-Berkeley library called another library in Hawaii to send them the microfilm or microfiche asked for by the requester and then sent it on to him or her?
BTW, it would be interesting to see if the birth announcement(s) of the Nordyke twins - who we know were born in Hawaii one day before Obama's putative DOB - are also in that same listing that same day. If not, why not?
