I like finding lists where people point out how obviously awesome libraries are, not just for the services they provide but for their institutional personas.  This list came via one of OCLC's blogs: "It's All Good."  Get it here: http://tinyurl.com/2eugbv or get the whole URL enchilada at:

If it's not obvious to you how varied libraries are perceived then by all means read the post and the comments as well.  Libraries are more than just books, right?  I'm sure you can add something new to the list too.
