Does your interest in Dragons extend to non-D&D/non-RPG books?
curious I ask because there happens to be a book that covers dragons and their kin.
Dracopedia: A Guide to Drawing the Dragons of the World . It's a non-RPG book that imagines an Earth where humanity co-exists with several species of dragons. Creatures with the Dragon type in this book are:
1. Amphiptere
2. Arctic Dragon
3. Asian Dragon
4. Basilisk
5. Coatyl
6. Dragon
7. Dragonette (domesticated)
8. Drake (domesticated, in this setting they're 'Man's Best Friend.

)
9. Feydragon
10. Hydra
11. Sea Orc (not an Orc, just an aquatic species of dragon)
12. Wyrm
13. Wyvern
