The Sweetwater County Library staff log, maintained since the building opened in 1980, includes hundreds of entries across decades. Recurring patterns documented in published interviews include books and small objects found on the floor after the library has closed for the night, voices heard in the conference room and upstairs reading areas when those spaces are empty, lights coming on by themselves and then turning off again, and the smell of cigarette smoke in non-smoking interior spaces.

One of the most-repeated incidents involves a custodian working a late shift who reported hearing an upstairs light come on while he was vacuuming downstairs. He left the vacuum running, went upstairs to turn off the light, and returned to find the vacuum missing — then heard a vacuum running upstairs. When he reached the upper floor, no one was there.

A second well-documented account comes from a Daily Rocket-Miner reporter who spent the night in the library on assignment. He recorded several unexplained clicks on a tape recorder left running in the conference room, and on the reverse side of the tape captured what sounded like a young girl's voice calling 'Hello!' — a recording later played for SweetwaterNow.

Local tradition holds that the activity intensifies in autumn and around library renovations. The 1996 discovery of additional remains during a building expansion was followed by what staff describe as one of the most active periods on record.
