Hi Bernice I just thought I would add a few practical words about our experience with these pests.
We have sporadic appearance of both booklouse (psocids) and minute brown scavenger beetles. They come and go. While we do not like them, after much experience, research and reflection (I can provide more info if you like) we tend to “mentally classify” them as “humidity indicators” or warning signs of potentially more damaging humidity related pests e.g. silverfish. That is not to mean we ignore them. In one area of the building we know why we have a small cyclical problem with the minute brown scavenger beetle (50%RH and hygroscopic cellulose in a fireproofing material on overhead metal beams). In the other room there is a small HVAC unit with an emergency drip pan underneath and a drain tube that leads to a bucket. We think the occasional drips of water that wind up in the bucket cause the spike in psocids. We hope to work with Faclities to find a slightly better system that the bucket. Ironically we try to call the booklouse, psocids because we find it a little less alarming and helps us keep it in perspective when we are monitoring their numbers.

Sorry, misspelled in this sentence. Ventral views and tarsal views would help, but the latter might be difficult to provide.

These look like members of the Latridiidae and probably belong to a species of Corticarina or Corticaria, possibly leaning toward a member of the first genus.
