Are you going to make this list of resources available online or is it for personal consumption only?
I probably will make it publicly available eventually, it just hasn't been a priority for me.
In addition to that, I would also suggest using https://zimit.kiwix.org. It's a very compact representation that has full text index support for convenient searching, the format is open and documented, and first-party readers are available on all major platforms. And for stuff like this, Kiwix might actually be interested in adding them to their official library at https://library.kiwix.org/ if you contact them.
