Interruption in service, Tuesday, May 15

Due to a planned power outage, lcsh-es.org will be unavailable for a while on Tuesday, May 15. The outage is scheduled for 6:00-7:00 a.m. EDT (-4:00). I will be out of town that day, so I'm relying on my coworkers to make sure the server comes back up. Please pardon the inconvenience!
