Do your players actually use them or just say, "Very nice", stash them and move on?
While detailed objects can be fun to make. they are a lot of extra effort that often gets passed over after a quick glance by players.
Greetings!
Yes, indeed, Greentongue, I use detailed wizard tomes, holy books, and mystical scrolls in my campaigns all the time. The players love the extra details that such items provide. There are often special attributes and powers that such books possess, and provide their owners with enhanced capabilities, as well as knowledge.
For example, I have some holy books which provide Clerics and Paladins with special prayers, enhanced spell capabilities, and stronger abilities in resisting and fighting against dark spirits and demonic forces, engaging in spiritual warfare, and providing communities or surrounding areas with stronger spiritual defenses. Some religious books provide deeper understanding of theology, enhanced powers of spiritual discernment, dream interpretations, understanding ancient prophecies, and greater powers in making use of Words of Faith.
Some Wizard Tomes provide enhanced knowledge of foreign languages, foreign cultures, ancient history, mystical lore, as well as deeper knowledge of golem construction, alchemy, crystal lore, ancient summoning rituals, and the harnessing and use of Ley Lines and Nexus Sites.
Different Mystical Books and scrolls can provide enhanced abilities to summoned creatures, access Mystical Gates, Nature Rituals, specialized recipes for magical tattoos, the crafting of enchanted beads and feathers, as well as various uses of mystical chants, tribal choruses, ritual body painting, sex magic, and using secrets of humanoid and animal blending.
Players also sometimes come across intelligent, sentient books, which provide a whole new dimension to the owning character's relationship to the enchanted, intelligent book.
The players in my groups love these kinds of extra details!
Semper Fidelis,
SHARK
