Thousands of genealogists have used the products created by Accelerated Indexing Systems. These slim books contain computer printouts of U.S. census indexes. Before the Internet, these were the primary method of finding anyone in the U.S. census records: first find the individual in Accelerated Indexing Systems' indexes, and then go to the microfilm image of the original census records, finding the page referenced in the index.
Ronald V. Jackson was the founder and driving force behind Accelerated Indexing Systems until the company was sold in the early 1990s. In addition to being a pioneer in the indexing field, Jackson taught genealogy at Brigham Young University for three years. He passed away some time later.
Jackson reportedly gave an undetermined donation to the Montgomery County (Texas) Memorial Library's Genealogy Department in his will. However, Jackson's heirs have not delivered the amount specified in the will. Cara Wood, assistant Montgomery County attorney, confirmed that the county is seeking funds owed to them by the heirs of Jackson's estate.
