The two books Chris referred to are:
- "Deutsche Nachtjagd - Personalverluste in Ausbildung und Einsatz (Fliegendes Personal)" by Michael Balss, self-published, 1997, no ISBN, softcover, 531 pages
- "Deutsche Nachtjagd - Materialverluste in Ausbildung und Einsatz" by Michael Balss, VDM Heinz Nickel, 1999, ISBN 3-925480-36-6, hardcover, 464 pages
As their titles suggest, these books focus on personnel and aircraft losses, respectively. The first one is hard to find, but the second is still available from Amazon.de. The second book includes corrections to the first one, and it also contains 40 pages of photos (5 in color.)
