This is a category that has a number of labels that are used: Archives, Catacombs, Stacks, all these titles do not seem to fit. These photos seem to come off more like long time friends, even like family members. I think of them as being in a treasured album, one that gets brought out on special occasions for reminiscing.
Here is hoping you will join me in returning to look at the, continuously being updated, album for a replay of a muse. Perhaps an introduction of all of this to a new viewer with whom you may wish to share your observations.
