Our recommendation is that six months notice be given for the selected “Snapshot Day” date. This allows plenty of time to generate interest among potential participants and it also allows libraries to schedule events that will attract numerous attendees. In addition, this is an opportunity to send out press releases to your local news outlets about the upcoming event.
We also recommend that you choose a specific date, but be flexible. We chose a definite date but offered all participants the option of choosing any date in a two-week window surrounding the chosen date. This generated excitement and anticipation as the target date approached, and unified the diverse libraries in the state as they worked towards a common goal on a shared date.
