Comments and Warnings Regarding the Transcribed Documents
1. The transcriptions from the Official Records, newspapers and books are from printed copies; therefore, transcription errors are someone else's.
2. Most other transcriptions are from the original (usually microfilmed) documents. Since these documents were in cursive writing, and were often written in a hurry, there are bound to be transcription errors on my part. Unless the meaning of the document is changed by a possible error in transcription, I have made little effort to resolve transcription problems (ie I have not tried to verify the initials of the names of various quartermasters). 
3. There are many more documents that I have not transcribed. There are orders to quartermasters to provide transportation for various companies and regiments in 1861 (I provide the ones sent directly to the railroad companies), there are many requests regarding charging various rates on various roads, and there are documents (particularly in press letterbooks) where so little of the document could be read that it seemed useless to provide what little could be deciphered. There are also documents where the ink has run together or the ink has faded away. Finally, there documents where the microfilm copy is so small that it cannot be read.
4. I have attempted to identify railroads and railroad personnel in the transcriptions. Otherwise, I have rarely provided editorial notes. For example, there is an order for certain Navy personnel to be given special assistance in transporting a shaft from Richmond to New Orleans. I understand from other sources that this was for the ironclad Mississippi, but since I have no document to prove this, I have left the raw data for the researcher to use on his own.
5. Almost all of the outgoing letters and telegrams from the Quartermaster General are copied in his letterbook and are transcribed. The incoming letters were logged, but most were not saved. The same appears to be true of the Engineer Bureau. The Railroad Bureau is represented by only a tiny portion of its correspondence. The Iron Commission is also missing in the records. The result is a very fragmented record, on the Government side, and an almost non-existent one on the companies' sides. This fragmentation is one reason I have posted the transcriptions.
