No matter who files the information (even the new guy!), you will find your documents easily and quickly!
Paper Tiger does not depend on any one person being able to accurately describe a document in a way that everyone else might. Even on an individual basis, the human brain does not think the same on any given day, therefore something that you filed under "car" one day, you might file or try to find it under "honda" on another day.
Paper Tiger allows you to describe an item in multiple ways, substantially increasing the chance that whatever you are looking for, you will find later! Paper Tiger gets even better when multiple people are using it, since by the time everyone has input into describing the document, it will have more than a single person's keywords for searching when it needs to be retrieved again!
