response: I'm not sure....I am grateful that so many are available to the public though.
history: Hey, i have visited a museum the other day, and it made me want to work in one so badly Hey there, really?  Did you know that the plural of museum can be either musea or museums?  They care for a collection of objects of cultural, artistic, scientific or historical importance.  And of course artifacts too! I know, i especially like history, speaking of that, i wonder if anyone knows when the first museum was opened?
knowledge: Many public museums make these items available for public viewing through exhibits that may be permanent or temporary.
