Does anyone have a numismatic literature inventory spreadsheet that works well for them? I've reached the point in my library where I don't know off the top of my head the contents of my library. I need an inventory list. I'd like to design one where I can sort it by Title, Author and Content. Before going through all the work of forming a database, and then having to redo it all later, I ask the advice of those that have a system that works well.
