Too far away to travel to the State Library?

Many of our resources must be used in the State Library only. Libraries may ask to borrow from our Genealogy and Local History collection on fiche. Libraries may ask for Table of Contents or specific pages to be copied or scanned for their patrons.  Staff will assist with general research for patrons. Staff will not do specific genealogical searching. Below is a list of names of professional genealogists that, for a fee, will provide researching services. Descriptions and contact information is updated annually.
