I wonder if there is any source for the following information concerning stock delistings in the US stock market:

* date and stock symbol of the delisting (required)
* covers at least 15 years history (required)
* should be a trustworthy source (required)
* reasons for delisting (optional)
* best as structured data like a CSV, export of some sort or API (optional, but preferred)

It doesn't need to be free, I am willing to pay for the data.

I know that there are similar questions, this is what I have found and tried but didn't work:

* CSRP database seems to have this data, but CSRP is not accessible to me
* <https://listingcenter.nasdaq.com/IssuersPendingSuspensionDelisting.aspx> this only shows current data, but no history
* Searching directly for Form 25 in SEC/Edgar also only lists the most recent data
	+ <https://www.sec.gov/cgi-bin/browse-edgar?company=&CIK=&type=25-NSE&owner=include&count=40&action=getcurrent>

Is there any other source I have missed?
