Misconceptions about Libraries -- all librarians are old ladies
While, yes, there are many women in the profession, there are also lots of men and many of us are not "old". And we're also not always grumpy (unless there are budget cuts, then we get a bit depressed).
And while many people might be "older" than the young patrons they serve, I think you'll find most librarians are young at heart, with a passion for stories and life. A lot of them are into technology and computers in a big way (more on that in a later post).
