Being one of two millennials working in this office, I find myself in conversations frequently about differences between the generations. Someone will make a reference about licking a postage stamp and I reply with "That's cray". This has led a co-worker to show me The Mindset List. Created at Beloit College in 1998 as a way for college professors to understand the "mindset" of incoming students, it has been eye-opening for myself.
A list has been created each year since 2002 and features 50+ items that young adults entering college that year know or don't know. The lists can be used with adults today to better understand the differences in generations. I think they would especially be helpful for libraries to not only understand their patrons but also potential job candidates. The authors have also written two
books (both of which are available in LINKcat) and frequently present the information as well.
The most recent list has some new slang, and I'll be honest that even I don't know what most of it means. Take a look at the lists and I think you will find them interesting as well.
