FOund it, yerss. it is in the Jedi Temple and Jedi Order databank entries.
"Headquartered on Coruscant, the Jedi trained, studied, and planned from the impressive Jedi Temple, a towering edifice rising high above the surrounding structures on the city-planet. They are governed by a High Council of 12 Jedi -- most of them Jedi Masters -- who contemplate the very nature of the Force.
Within one of the outer spires convened the Jedi High Council, the governing body of the order. From its circular Council chamber, a ring of 12 Jedi held court, monitoring galactic events and contemplating the nature of the Force. It was the Council that held final authority on Jedi missions on behalf of the Republic, and on whether prospective candidates were worthy of training.
In its final years, the Council was led by senior Jedi Mace Windu and Yoda, two very powerful Jedi Masters. At the time of Palpatine's ascendancy to Supreme Chancellor, the Council contained such Jedi luminaries as Ki-Adi-Mundi, Depa Billaba, Eeth Koth, Even Piell, Saesee Tiin, Yarael Poof, Oppo Rancisis, Plo Koon, Yaddle, and Adi Gallia.
Aside from the Jedi High Council, there was the Council of First Knowledge, the Council of Reconciliation, and the Reassignment Council."
However, see my new thread on Mace for an objection to this suggestion.
Incidentally, Eeth Koth was going to be the head of the Council
