That is the Birth Index of Hawaiian Birth. That is not the Index obamas name would/should have been in.
There were four different types of Birth Index Books.
The article at the link states it's a list OF THE NAMES OF PARENTS...(with the father's names redacted) so I take that list and the others at the website to be useless.
I’m going nuts...the article states the list is the names of the parents, but BOTH parents names are redacted!
