Some examples include image generators. Here are a couple of examples we created using big huge labs.
Another popular mashup tool is Google maps. Have a look at this example from the British Library called London: a life in Google maps or this public library finder from North America. Voicethread is another type of mashup tool which could be really useful for adding information to digital objects from your local studies collection.
Discover: Using Big huge labs, create a mashup and add it to your blog. Hint it will save the image to your desktop so you will need to upload it to your blog from there. Blog about how you could use mashups at your library.
Adventure: Find another example of a mashup. Blog about how appropriate it would be for your work.
