Narrative:

We recently flew into sfo; and there appears to be an error in the taxiway designations and the depiction on the 10-9 airport diagram. The taxiway that is charted as 'B1' on the 10-9 page is actually labeled as 'Q' on the airport signs on the actual taxiway. We did not see any taxi sign labeled as B1. Also; the taxiway labeled as 'Q1' on the 10-9 page; is not even marked on the actual taxiway in sfo. I could be mistaken; but I would like to request that this issue be looked into to make sure that the signage on the diagram exactly matches the actual taxiway signs on the airport.
