Florida Amended Birth Certificate ( False Information ?? )

I would like information also regarding amended birth certificates. I was adopted in 1957 and if the information is correct on the amended bcert, I was born in Dunedin Fl. (Pinellas County). The amended bcert that was issued does not contain weight, time of birth, delivering drs. name or hospital. Any information would be very helpful. I've read that the amended bcert # is different from that of the original and that the amended bcert can be "matched" to the original. I read (and followed up but to no avail) that there is a book that cross-references the amended bcert # with the original #. I've read that it's rare (but it does happen) that the amended bcert contains false information. Please feel free to email me and good luck.
