I often have the situation in which I find information that I do not wish to automatically relegate to my research notes. In fact, sometimes, the line between material that belongs in research notes and that which belongs in formal findings is clearly blurred. In these cases, I believe that a citation should be considered. But how and using what format ...
FreeBMD indices are known to be simple extractions from digital images of the U.K. BMD index books. Technically; information obtained from this source belongs in my research notes. I can't always justify ordering certificates for persons not in the main line of descent, nor can I immediately locate the related parish records. But; I do wish to record the contained information as an entry in my formal records (at least temporarily), as others typically don't have access to my research notes. Is there an accepted method to do this that clearly indicates that the information is not intended to be exact, but rather a finding aid that could/will be followed up?
A more important instance is the relatively recent GRO birth and death database. It is definitely not the same situation. In the case of births, it may explicitly state the maiden name of the child's mother. This information was not present in the images of the index books and indicates that it was very likely input derived from the actual records. This makes this source more than a simple finding aid and one that deserves more visibility. Unfortunately; the GRO does not explicitly state the source of the non-index information. How can this be handled using a citation?
