I'm pretty impressed with this overall - the spells are organised into the categories you'd expect, and while they're mostly presented with little context or guidance, the first hundred or so pages are dedicated to some of the core principles, tools and techniques of magic which is pretty useful. Even if you're not new to all this, it's handy to have the information easily accessible.

The book is 20 years old, so fair warning that it does play fast and loose with historical accuracy and there's some casual cultural appropriation that wouldn't fly today, but with the focus being on the spells themselves the commentary is brief and you don't have to suffer through more than a few brief mentions towards the beginning. That said, it's no more cringey than any other occult book I've read, and at least Illes actually addresses the concept of hexes rather than reciting the same tired old "REAL witches would NEVER" line.
