Partial content sharing with players

I have a lot of D&D books and other content that I own in Roll20. Some of it is player oriented (like Players Handbook) while others are GM oriented (like Monsters Manual). I would like to make player oriented content available for the players in the in-game compendium to look up spells and drag them into their character sheets. But at the same time they should not be able to search for monster stat blocks.  I cannot figure out how to set this up. If I set the Content Sharing to NO, the players cannot see anything in the compendium. If I set it to YES, players can see all material I have included in the game, including Monsters Manual.  If I set the Content Sharing to YES to allow them access to Players Handbook, but then remove the Monsters Manual from the game to hide monster stats from them, I - the GM - can no longer find the monsters in the in-game compendium to drag and drop monsters into the game. What am I doing wrong here? I assume it must be possible to share some books but not all, and still have access to the material I have bought in Roll20. Thanks for any help or guidance .

There's nothing stopping your players from purchasing (or accessing pirated copies online) all the material in the DMG, monster manual, etc. on their own, outside the game. Having the compendium available in-game just allows them to drag-and drop that material onto their character sheets. Restricting what they can see in game won't stop them from metagaming. All we can do is ask them not to.

Hi Henning E.,  You are not doing something wrong.  Here are the options:  * Red: not accessible in the game by anyone (including the Game Owner) who owns the product. They may still access it out of the game or in other games if they own it.  * White: Game Owner does not own it, but anyone who does may use it in the game.  * Green: Game Owner owns it, and has listed it for sharing. (Must also require the Content Sharing be set to Yes and there not be too many people in the game.) There is no option for the Game Owner to not share content while still allowing the Game Owner to see that content in the Compendium.  I agree with Rick A., ask your players not to look. It is pretty easy for them to do so without you sharing content.
