I am researching my family, my husband's family, and my stepdad's family, so I am amassing quite a lot of material. I have my documents organized in binders by family name, with dividers for each type of document (census report; city directories; birth, death and marriage records; etc.). I have a sheet in the front of each section that lists what is there and what names appear on the documents. It seems that organizing looseleaf books by a person's first name would be a better way to go; documents that list more than one name could be placed in separate sections by type of document and would not have to be duplicated and placed under each person's name. A reference page under each person could list where these other documents may be found.

Several questions:
-Does anyone see a problem with this type of organization?
-Should documents be assigned reference numbers?
-What do you do when a woman marries and assumes a new name? do you file her under her family's name until she is married and then under her husband's name after she is married?

You may want to look at the LDS site. They have some very useful free forms to use for the organization of family records. Another good resource is a good book on basic family research. They frequently recommend good organization practices.
