Where do you find the button for viewing the history of street view? Is it on the normal street view interface, or do you have to use an additional service/hackery?
Top left corner, the box with the address of the place you're looking at. Its bottom line is a clock icon and "Street View". Click on it and you get a slider with the available pictures. Place the slide on a date and click the thumbnail image to update the main view.
If there is no clock icon, there is no history for that location.
