Not sure if this is exactly what you'd call a template- but it is very clever and timely.
Basically a plug and play form for libraries to create web ready reference guides- seems to be very popular among libraries- at least judging from the Web4lib listserv.
from the Springshare website:
All institutions using LibGuides are connected in a global content network spanning 500 libraries with 8,500 librarians who have created 27,000 guides with hundreds of thousands pages available to browse, share, and learn from. Librarians can use any existing guide as a template when creating new content, and they can share specific pages and content bits with each other, and collaborate when creating guides.
LibGuides is a fully featured, easy to use, web 2.0 content management and publishing system. It combines the best features of social networks, wikis, and blogs into one package designed specifically for libraries. Check out these features of LibGuides.
