Thank you to all the people that contributed answers to my query on web page permanency. Like William Thompson, I have been around computers for a long time. I started off with a computer with no hard drive and programs run off floppy disks and I have seen floppy disks, tape drives and zip drives pass into oblivion, so I have little faith in the permanence of modern technology. I agree that PDF files appear to be a good option, although they have only been around since 1993. Jim Loudon suggested ASCII text files, which I think is a good suggestion as they have been around the longest. I think the suggestion of Cloud storage is a good suggestion, particularly if several sites are used. The distribution of paper copies, to relatives and institutions is necessary and I have found some of my best genealogy information in Public Libraries and FHS libraries. I intend to stick to a simple html/css format and steer clear of Javascript and other add-ons. I also intend to pursue the Wayback Machine web site archival approach through http://archive.org, which is also a good source of genealogy material. Thanks again to everybody.
