1a - Where is US government website where person can requesting free
copy of their MIB (online or by phone). And I don't mean MIB.com. I am
looking for government website that would reference something like
MIB, i.e. for instance Federal Trade Commission website references
There isn't one.
The right to medical information is a right you have vis-a-vis individual heath care providers and insurance companies that have your medical information. The U.S. government does not have access to this information and doesn't facilitate you getting this information, except that you could sue in federal court to get it if the person required by law to provide it to you didn't give it to you.
(The fact that the U.S. government does not have access to individual health information is one of the reasons that major medical research studies that capture a sample of the entire population of a country for a given time period are often done instead in foreign countries that have comprehensive medical records databases. In the U.S., the best possible alternative is often to look at the medical records of servicemen and veterans who received government provided health care, or to create very large voluntarily long term studies of populations such as doctors and nurses.)
Even in the case of credit reports, the government website merely ends up directing you to a private sector website maintained by credit reporting websites and is not a government website.
1b - Where is US government website where person can requesting free
copy of their other personal records (online or by phone)
You can apply to the U.S. government via one of the IRS websites to get transcript of your past tax returns for a certain number of years.
You can apply to the Social Security Administration to get your earnings history for Social Security purposes and I think that can be done from their website or by telephone.
There is a U.S. government website called PACER at which you can get copies of all non-sealed filings in all federal court cases, and all filings in court cases to which you are or have been a party.
There is U.S. government website at which you can ascertain whether or not a building, including your home, is in a flood plain.
There is a U.S. government website that allows you to locate people who are currently incarcerated in federal prison.
There is a U.S. government website that allows you to review census data from time periods when almost everybody is dead. I believe that old immigration records can also be accessed in this manner.
There is a phone number at the Veteran's Administration where veterans can ask about their personal veteran's benefits. I'm not sure if that have a website from which they can do so yet. Last time I checked, a long time ago, they didn't.
There are several websites and phone numbers that federal employees can access to get their personnel record type information.
This is absolutely not a comprehensive list.
It shouldn't be hard for you to research yourself the current web address for these sites which changes fairly often anyway.
You can get many other kinds of information from the U.S. government that is about you via the Freedom of Information Act (a.k.a. FOIA), but generally speaking, this information isn't available via a website or by phone. Usually, you have to request it in a written letter or application unless a new website allowing you to do this that I don't know about has been created recently.
