The Middle Country Public Library’s treasurer does not provide monthly reports to the board of directors, and the nature of her employment is unclear, state auditors said in a report released Tuesday.

In a 10-page report, auditors said they could not determine whether treasurer Martha Vail was an officer of the Centereach-based library or an independent contractor. The report said Vail had been paid $3,176 for a one-year period that ended last June.

The audit said Vail should be sworn into her post and named an officer.

“Because the treasurer is responsible for the care and custody of library funds, the board cannot delegate these functions to an independent contractor,” auditors said in the report.

In an interview, library director Sophia Serlis-McPhillips said Vail is an independent contractor, but she was sworn in after the audit was provided to library officials. Serlis-McPhillips said the board has not decided whether to change Vail’s job status.

She said she had reviewed the audit and library officials would “comply with as much of it as we can.”

The library has an annual $14.6 million budget and serves 62,000 residents in Centereach, Selden, Lake Grove, Coram, Farmingville and Port Jefferson Station.
