Mashups use in the library setting

I think there would be many opportunities to use mashups in the library setting. A calendar could be used to promote author talks - the book cover as the photo and then the date of the visit circled. Local history sites could be marked similiar to British Library's 'London : a life in google maps'. As with all of the Web 2.0 tools - time, expertise and creativity could certainly enhance library homepages .
