I have about 15 binders full of birth certificates, marriage certificates, death certificates, photos, newspaper articles, that's before the internet days, 35 years ago and then using a typewriter, the family history typed up, and then added to them printed off the internet various useful information. As I am still adding family members here, I use my 15 binders as a reference nearly every day. While a lot of my family history is online, I do get a bit worried if I ever lost it all.
