Copyright issues aside, it would seem to me to be sensible to preserve these charts for posterity in digital form by photographing/uploading/scanning. Then if it is decided to make them available to other researchers, even if only to those who are members of the IOMFHS, that could be more easily done. It would also be more cost-effective to share charts electronically than by photocopying and mailing. They could even be put onto cds and sold to raise funds.

They sound as if they are the product of a lot of intensive research and it's possible making them available could save a procession of researchers from stumbling along the same paths. Even if Constance Radcliffe didn't intentionally do this research to benefit other family historians as did Brian Lawson, it would surely be a shame for such seemingly useful work to be lost.

Just my personal thoughts on reading this extremely long topic!
