In addition to microfiche, newspapers also keep BOUND copies of their prints in the main office. The Smithsonian and/or Library of Congress should have independent archives as well.
REGARDLESS...
Ann was just a little over 18 years of age at the time of Barack Jr's birth. She had only been in Hawaii barely a year -- if she didn't actually leave for Washington state (or elsewhere) in Spring of 1961 before Obama was born.
She probably would NOT have a Hawaiian Drivers License to present -- even if authorities asked for it by mail or in person (which they probably would NOT have) to verify the address of residence on the newspaper ads of 6085 Kalanianaole.
Regarding Ann having a form of ID (Hawaiian Driver's License) to prove her address of residence to authorities if the baby had ACTUALLY been born in Hawaii ...
It was far too expensive for many residents to own and operate a car, then as it is now, in Hawaii. Ann's parents were a junior escrow officer (mom-Madeline) and a junior furniture salesperson (dad-Stanley), paying for college tuition. The father (Barack Sr) couldn't/wouldn't support the mixed-race child child either. THERE WAS NO REASON FOR ANN TO HAVE A HAWAIIAN DRIVER'S LICENSE THAT WOULD REPORT 6085 Kalanianaole. People take a taxi, bus, bike or walk because the distances are relatively close on the island:
The address, 6085 Kalanianaole, is AT BEST an address of residency, reported by mom or grandmother, and probably via the US Mail. It does NOT denote a location of birth, or a state/nation of birth.
The Hawaiian newspaper ad means NOTHING other than where Ann claimed to have lived -- nothing more.
The ad does NOT prove that Obama is a NATURAL BORN CITIZEN.
