Have years of family Research that you want to ensure is preserved for future generations.
There are various ways you can go about this.
Donation to the Family History Library
One way is donating items to the Family History Library (preferably in pdf format)
This link is helpful to learn more about that:
Family Search Memories/Albums
BUT also consider uploading items you have to FamilySearch Memories. This can be done in much smaller bits and pieces, document by document - - linked to specific people - rather than one huge book or set of paers you want to donate - that ends up being very cumbersome.
see these links:
Pedigree Resource Files
also for any data you have in computer database format (Ancestrl Quest, Roots Magic, FTM, PAF etc.)
The pedigree Resource File Area is a way to preserve your data files
