Ruth - what a great impulse, and thanks for the offer to share the information. The best thing, it seems, would be for people to work on transferring the information contained in those books to wikitree, with citations, etc. Do you live in an area where there might be high school or college students who would be willing to take this on as a research project? If you could recruit folks to work on this - and if you live in Louisiana, there might be some add'l support from local or state organizations - it would be fantastic.
While I agree that it would be great to donate them at some point to an institution, you've said you don't want to do that now, and it doesn't really serve the purpose you'd like - a library will stick them on a shelf or in a reference room somewhere and is unlikely to disseminate it. But perhaps if you could promise a future donation to a library, you could extract a commitment from the library to put together the group of interns to help get the info into the internet.
Best of luck, and thanks again.
