I loved TLDP and it was key for me coming up in Linux. I'd say the closest thing now is the Arch wiki (https://wiki.archlinux.org/ https://wiki.archlinux.org/) . On Arch the user chooses really everything after the package manager, so you'll find good, clear doco on whatever combination of tools your distro uses. If you're looking for help with package managers, you're stuck with the distro's own documentation. :)
