I recently had a chance to look at this CD subtitled 'The War of the Rebellion: A Compilation of the Official Records of the Union and Confederate Armies.' It includes the records of that name along with Dyer's highly respected Compendium, Fox's Regimental Losses, a user's guide to official records and an index to records edited by the National Archives. This is not inexpensive -- $70 plus shipping. It works on both PCs and Macs they say. It is searchable but not particularly intuitive. I THINK the average user would figure it out. They claim 9,000+ people own it. All of the records it contains are in the public domain and most can be found at larger libraries but, of course, nothing beats having them at home and nothing beats the speed of searching a CD, even if the search engine is not state of the art. It says there are 'extras' on the CD with Access or Dbase IV compatible databases with 'over 12,000 particular military activities' and 'a large listing of Fox's statistical data.' [How many people have Access or Dbase IV on their home computer?] Several records from these sources are already online at The Illinois Civil War Project. It contains regimental histories and other information [for Illinois -- I believe other states are doing similiar projects and there is also a national project]. http://www.rootsweb.com/~ilcivilw IF your ancestor was an officer or otherwise caused notice [such as a private Samuel Downing who was murdered in Missouri] you may well find information by searching for that name. If you are interested it is published by Guild Press of Indiana, Inc. which is in Carmel.
