Wookieepedia probably. And the Chimaera was an ISD, it was at Endor.
Ah, there we go. Wookieepedia offers references to other ESD's from 3-4 ABY. The passage: During the early years of the Galactic Civil War, several other Executor-class ships were built and fielded. A Rebel strike destroyed an Executor-class ship, upgraded with cloaking technology, while still under construction at Fondor in 3 ABY.[41] Another Star Dreadnaught with cloaking capability, the Terror, was already operational by 3 ABY.[42] The Vengeance lead a task force around this time.[43] Towards the end of Palpatine's glory days in 4 ABY, other Executors were noted as well. The Guardian was tasked with protecting Coruscant,[44] the Annihilator served in close vicinity to Kuat,[45], the Reaper led Scourge Squadron on its patrols in the Outer Rim Territories[46] and the Brawl was given to Admiral Zsinj by Palpatine himself.[47]
