I know it is more niche to the online/websites POV, but “Don’t Make Me Think” is a book that needs to be somewhere in the lines of “The Design of Everyday Things.” Of course, I re-read the latter as reminders and catch-up readings.
Ha ha, I love even the cover photo of “The Design of Everyday Things.”
I was surprised this wasn't on there, even with a caveat that it's for online sources like you note.
