[StarWars] What Happened to the Jedi Holocrons in Revenge of the Sith?

So in Revenge of the Sith we see Yoda and Obi-Wan in the temple. Both of which Jedi masters and have the ability to open the Vault in the Library and take them for safe keeping. Did the do this or just hope that the newly appointed Emperor doesn't destroy them and the Chosen One would be able to find them and restore the Jedi Order? Seriously, all the Jedi's secrets are kept in them, where did they go?

Much of the Jedi Archives were destroyed during Vader's raid on the Jedi Temple at the beginning of the Great Purge. Surprisingly, this was not done by Vader or the 501st, but by the Jedi, who wanted to keep as much information as possible from falling into the Empire's hands. It is likely that many of the holocrons hidden in the temple received the same treatment. The information that survived was turned over to Palpatine, who from what I've heard made frequent trips to the Archives. Any holocrons that weren't destroyed were likely either smuggled out by the few Jedi that escaped or ended up in Palpatine's clutches.
