Strategy guides

I am a proud video game Collector and I have around 140 strategy guides including around 40-50 hardcover collector’s Editions and one of the hardest pieces of information to find out about video games is whether or not a specific game has an official strategy guide or not and if it does then who wrote it and what kind of guide is it like paperback, hardcover and/or collector’s or limited edition plus how many guides were made for the said game and what kind of guides are they...I would love to find a dedicated, accurate, fully detailed and enormous list of strategy guides covering all platforms and games
