As far as book recs, what books are the least "suspicious"-looking title-wise, like in a won't weird your family out too much way?
This is an interesting question because I'm objectively the least weird person in my immediate family as far as books go. But I'll give this a shot! I'm gonna avoid books with "witch" in the title, but honestly, I have no idea how wary your family may be of books.
The Farmer's Almanac of the year: Once you get past the advertisements, there's a lot of practical growing advice and a surprising amount of magic-related stuff. Well, astronomy/astrology-related stuff, but still. I started using these as of earlier this year and have both the 2022 and 2023 editions. Jasper Category: Regional/Personal Practices.
Roots, Branches & Spirits by H Byron Ballard: My first introduction to the concept of folk magic was this wonderful book on Appalachian folk magic. It inspired me to look a lot more local and eventually led to me finding the Ozark Magic series by Brandon Weston. I'm not sure if it's particularly telling to the casual observer, but it's a fascinating look at someone's personal journey into their local magical tradition. Jasper Category: Regional/Personal Practices.
Badass Ancestors by Patti Wigington: I've gone over this book before, but if you're trying to learn about ancestor work (or even just your ancestors), it has some valuable resources and ideas of where you can look. It's useful enough that it's made it into my reference stacks. Jasper Category: Miscellaneous.
Willow and Sage Homemade Bath and Body: More of a magazine than a book, my May/June/July 2022 edition is a very practical guide for making all kinds of products. I look forward to actually trying out the recipes. It's not magic by any means, but it's helpful. Jasper Category: Miscellaneous.
Pretty much any mythology or history book: We all have those periods of time that we go absolutely batshit over mythology and history, right? Right? Yeah. This is also where my copies of the Homeric Hymns, the King James Bible, and others are located. Jasper Category: History, Religion, and Mythology.
Do I Have To Wear Black? by Mortellus: Likewise, this is an in-depth look at the various religious funerary and mourning practices, especially in modern contexts, brought to us by someone who actually works in that field. Jasper Category: History, Religion, and Mythology.
Regional ghost stories: I happen to have several Missouri-based or Mississippi River-based books on ghosts. These help take a look at folklore, history, and how things evolve and change over time, as well as how they stay in the public consciousness. Jasper Category: History, Religion, and Mythology.
Regional farming/planting guides: Similarly, I'm in Missouri, so a good number of my gardening guides are either about planting indoors, planting edible plants, or planting things that work great here in Missouri. Jasper Category: Gardening and Plants.
Historically- or locally-significant books of folktales, poetry, and fiction: We've got Edgar Allen Poe's complete works, we've got the Brothers Grimm, we have five great Greek tragedies in one book, we've got Horrible Phobias Lovecraft's works (may he rest in the racist squallor box and may he spin in his grave over everyone wanting to kiss his monsters), we've got Dante, we've got the Dictionary of Obscure Sorrows, we have "Jasper ran out of money but keeps trying to wipe out the book store's shelves of any significantly-old book with a new or fancy cover EVEN IF THEY ALREADY OWN IT." We've got the range. These are great for summoning up specific feelings or memories, for coming up with chants, for pop culture magic, for everything! And if anyone asks, you're just a fan of the classics! Jasper Category: Old Shit.
Unfortunately, most of my beginner-focused books, my tarot books, my spellbooks, and my correspondence-based books are a lot less low-key.
I hope this gives you a few ideas! I'm sorry if this isn't particularly helpful, I'm just not in a place where I have to be worried about people seeing that I practice magic. I mean, I have 62 tarot and oracle decks lined up on my shelves, it would be foolish of my family to NOT notice.
