Florence city buses

When I was in Florence last fall, no one had route maps for city buses and trams. The TI said they had been trying to get them for months and they hadn't been reprinted. I'm not very adept at public transportation, and not having a map was a signficant issue on that trip. I'm going back next month. Has anyone been able to get a bus map in Florence recently? And if so, where did you get it? Thanks
