Don't, the only records showing what citizen has what firearm by S/N are at the local guy down the street who functions as the community's FFL ~ period!
addendum: FFL's A/D books & 4473s are not alpha sequenced but by date received or sold and ATF does not allow FFLs to use electonic A/D databases to do a quickie search by say last name or S/N which going to the FFL directly, depending on their sales volume would be a Herculean task.
I... don't know of any rules forbidding FFLs from maintaining a database parallel to their bound books? In fact, it looks like FFLs can use databases to replace bound books - unless this ruling got superseded: https://www.atf.gov/file/11226/download
