It's just, in the three years I've been working at Bartow Library as the Reference and Computer Tech Support Librarian, I have gone through four boxes of business cards. In the years that I've had company business cards - since 1997 or so with Broward County up to 2003, up to 2006 at University of Florida, and between 2006 to 2008 with Pasco County - I barely finished off the single box of cards each place had given me.
It's a difference in the audience now. Previously, the business cards were just for professional courtesy between fellow librarians for conferences and conventions. At Bartow, it's the public who take the cards so they can call back later to schedule One-on-One sessions to teach them how to use their computers and tablets, or fix any glitches in the software/operating system (I don't have the tools or supplies to fix hardware, sorry).
Still, it just seems... nicer, to be able to say I'm handing out so many business cards like this.
Now, if I can just hand out my bookmarks promoting the ebooks I've got on sale at the same rate as my business cards...
