I wish to thank everyone who responded to my request for a current address for AIS - Accelerated Indexing System - and there were many of you! First I must apologize for a mis-typing. I MEANT the 1870 Texas Census not the 1860 Texas Census. Many of you pointed out that the 1860 Census index is only 1 volume, not 6 or 8. AIS has been purchased by Heritage Quest in Utah. Phone # 800-760-2455. I verified the phone # and the fact that they had bought out AIS. However the 1870 Texas index is now on 1 cd and they prefer to sell the cd rather than the printed versions. They are checking to see if any of the printed volumes are still available. Again thanks to everyone who offered suggestions and shared information. Genealogists are cerrainly a very sharing community. David
