Reddit user DisneyLines has created an awesome website for Fallout 4 players.
Called Fallout Tracker, it allows players to keep track of all collectibles within the game and check off which ones they have gathered.
If you want to know where to find all the collectibles such as Bobbleheads, Magazines, Weapons, etc., it gives you that information as well. It even has links to videos which are a visual step-by-step guides. Not all videos have been added, as it's still a work in progress.
You can even save your data across multiple devices when you register, and DisneyLines promises he won't send you any "annoying fucking emails" when you sign up.
More collectibles will be added when discovered along with data such as weapon damage in the future. The site contains a few spoilers, but DisneyLines plans to add a code which will only show the locations when you hover over it with your mouse.
