Recently I saw a post in the german stackexchange, that was about Resources for learning German. And then I asked myself, if it could be possible to make such a post for chemistry, too. It has previously been discussed here.
The post on the main site is a community wiki and contains resources for learning chemistry, like websites, books, etc. that can later on be used as a reference for many answers or comments. It is locked to only allow the answers that have been created in the template to be edited. No new answers can be added.
This is also where this post comes into play. The basic outline of the big list can be found below. It shall contain the most recent state that is going to be in the main post.
If you have questions or suggestions, please leave an answer here.
During the planning phase, this post could have been edited by everyone (> 100 rep) to include, remove or refine items. If you agree with the contents you can still leave a vote. If you disagree please add a new answer (so that this post get bumped on the active tab).
The actual post can now be found on the main site.
