How will you categorize your personal collections of letters, photographs, documents, and the like? Most commonly, your materials will fall into these three categories:
Consider using the person's birth name as well as birth and death years. Genealogy software will provide for married or changed names, but to keep all of your resource materials about the person in one place, most people use the person's birth name. Note, too, that many names are used multiple times in families so birth and death dates are really helpful.
Place names change frequently in the course of history. You can file place material either by the current geographical name or by the name in use when your ancestors lived there. A good gazeteer is very useful for genealogy whether it is in print or online. You might be surprised how good Google is for identifying places.
Your family's story may be tied to specific events in history. You might have volumes in your book collection or articles in your files.
Depending on your family's history, you may also have primary source materials in other areas such as "history" or "culture". If you don't know what metadata to use, you might try using subject headings from the UCLA Library Catalog.
