Hi Megan My practical experience agrees with Richards email.
We occasionally get outbreaks of booklice that seem to grow quickly and then disappear in our Archives storage. Consultation with CCI has convinced us not worry about these as a risk of major damage, because the mouth parts of the booklice are so small it would take a major prolonged infestation to cause damage. For that reason we have rebranded them as "Psocids" not book lice, just to keep them it in perspective. However, they are a real indicator of RH issues that could lead to more significant pest damage from silverfish or springtails. In our case we simply could not figure out how we would have a pest that was an indicator of high RH in a storage vault with good RH control 35% plus/minus 5% winter, 45% plus/minus 5% summer. We then started looking for sources of "localized high RH" and sure enough with that perspective we found it (a plastic tube, designed to carry overflow water from a drip pan under an localized HVAC unit carries overflow water into a bucket "inside" the storage room e.g. occasional wet damp bucket breeds booklice). With this knowledge we are trying to get the wet damp bucket to be located outside the storage room.

Megan,
Book lice should be expected in and around any museum, library, office or home. A few in a library setting shouldn't necessarily cause alarm, but it would be wise to continue monitoring the archived materials as well as the general environment. If you see book lice more than occasionally in the archived materials, then consider trying to reduce the overall humidity in the facility. That is usually the most practical and acceptable means to maintain the population of book lice at or below an acceptable threshold level. I realize this can be challenging in Bremerton, but it is possible.Good luck.

The area we found them in has a number of large map cases and file drawers, but I could not find any traces of them inside the actual cabinets. Aside from setting more traps throughout the area and placing silica gel inside certain cabinets(to bring down the relative humidity), I have no idea what to do.
