If you're in the UK, next-time you're forced to do a cull, try to see if you can find (or just start) a Bookcycle/Shelfcycle nearby. There aren't many yet but they're growing. It's a charity explicitly designed to do a better job of valuing donated books than existing infrastructure. They worked out that places like schools in developing worlds can often make great use of the books that other charity shops would destroy because they don't sell quickly in UK charity book shops. So Bookcycle sells the ones that would to raise funds to send the ones that wouldn't as a donation to communities that would value them. They try really hard not to destroy any book that someone might still find value in somewhere.
Right now it's a little harder to answer as the support resources for learning Godot are all in the process of being updated from the way things were done in the old Godot 3.x to the new Godot 4.x system. The changes aren't huge from a learning perspective and largely I'd say the Godot 4 way (where it differs) is actually a little easier to learn.
For example, this is a wonderful free interactive course on how to program in Godot (which is one essential skill for making games in Godot and probably the biggest sticking point for new developers) however it was made for Godot 3.x (I think 3.5 specifically...) so... It would be a good place to go learn the basics of how to program in Godot but you'd have to do so with the awareness that you'll be learning some stuff that you'll need to update your knowledge of at some point for Godot 4.0 (for example, when you are programming for a character to move on screen there's a command you can use called "move and slide" that tells Godot that you're done setting up for it and it should make your character do movement stuff now. In Godot 3.5, you need to explicitly tell it to use the movement speed you just told it to decide how fast your character should move. In Godot 4, you just tell it the movement speed then tell it to do movement stuff and it does it. Slightly quicker and easier in Godot 4 but if you use the exact same code from Godot 3.5 it'll throw up an error until you figure out what needs to change.)
Anyway, here is the course for Godot 3.x (fyi, you can still download and use Godot 3.x if you wish, but you will eventually want to switch to Godot 4, so it might be better to just use the slowly appearing new educational content for that rather than the more extensive stuff for Godot 3.x... It's just a transitional time right now.):

They are also working on a new Godot 4.0 version but because the course actually recreates the effect of what you are doing live as though you were working in Godot (by using a modified version of Godot in the background) it's a lot of work. Surprisingly it looks like it might only be a couple of months before some sort of 4.0 version appears.
In terms of Godot 4.0 tutorials, Heartbeast's first one (a simple black and white 2d platformer) is 99% finished (I think he has one final video to do but it should be out long before you could catch up to it if you started today). I haven't watched it but his stuff is usually quite good and often recommended:
