Where is the BC Library Off-Site collection? Is it in a lair underneath the Chestnut Hill Reservoir?

Books and water don’t mix, so no, but I hope someone has a lair down there. There are three offsite locations. One is in the Kenny Cottle library on the Newton campus. One is a storage facility in Danvers MA. And one is actually in a non-public part of the first floor of O’Neill. That’s why delivery times are a little variable.
