Binder or drives?  Depending on your personal preference–and storage space limits–you will need to  determine whether you capture all your data electronically, or print out everything you find.  For my direct lines, I have printed out the important documents and kept an electronic copy.  All those distant cousins and the people who I do not know how they fit into the picture yet are all digital copies.

One of the main things I have learned about capturing digital copies is to make sure that if the image is captured using a program which saves in a  special format, that I  am able to convert it into a jpg file.  Many times I have had to hunt down a patch to convert the files into a jpg.
