My latest interest is in the OAF ('99 Serbia) campaign, so the latest additions are...

General Spasoje Smiljanits: Agressija NATO (Serbian & Cyril)
Bojan B. Dimitrijevic, Jovica Draganic: Vazdusni Rat Nad Srbijom 1999. Godine (Serbian & Latin)
Benjamin S. Lamberth (RAND): NATO's AirWar for Kosovo

... these are highly recommended about the '99 events.
