A printed one is an exercise in futility since your owned library will probably change on a regular basis. You can create a highly useful one on your local computer or network with most font management software. My personal favorite is
Typograf although it requires a modest fee to have a full running copy.
This approach allows one to sort their fonts into type style categories such as the Serif group shown above. It also allows one to enter any given text string for type design selection or for font matching.
As an aside, and I think many here will agree, it is a mistake to have any way for clients to sit and browse your available fonts. That is the job of the designer and will only lead to confusion and problems when put in the hands of the client.
