ICYMI is Twitter-speak for "in case you missed it."
A few days ago, someone on the TLC listserv posted a link to a whole collection of applications that various librarians use to select student library workers.
The folder can be found here. It includes forms, parent permissions, teacher permissions, job descriptions, etc.
Really useful stuff!
