Before mods, before wikis, the game’s native user interface contained its own "Codex." Located in the pause menu (the second tab with the tree icon), this is the official record of everything you have discovered.
Whether you are using the vanilla to track your first Rainbow Trout, installing the Stardew Valley Codex mod to turn the game into a hardcore RPG, or simply using a Wiki as your external Codex to find out that "Sebastian loves Frozen Tears," one thing is clear: The pursuit of knowledge is what drives the game forward. stardew valley codex
