Your Conference work is still not done! You can’t expect to develop relationships just by bumping into people for a few minutes. If you haven’t done it already, now’s the time to follow up with some of the people you met. I know you’re busy, but it doesn’t take too much time to send off a few emails, add some Facebook friends, or praise your own staff if you’re a Dean or Director. Look how easy it is–
“It was great running into you at ACRL, let’s get together again soon.”
“I enjoyed meeting you in Baltimore. It was great to hear about….”
“Thanks for ….
“I’m glad you came to my talk, here’s those slides I promised…”
“Thanks to everyone who represented our library at ACRL….”
Of course put these into your own words and be genuine. If you want to work on a new project with someone, try to propose some way of going forward. Now excuse me, I have some emails to write!
