Barnes & Noble runs the Web site Quamut:
A Quamut is a concise yet comprehensive guide to a particular subject, such as Buying a Home, Personal Finance, or Making Sushi. Every Quamut is professionally written, edited, and fact-checked, so you can trust the content.
Their free online, but it costs you $2.95 to download one as a PDF and $5.95 if you want to buy one as a laminated card.
They also offer a daily free PDF download. Today's is on "aromatherapy," which doesn't speak well of B & N's "fact checking." Aromatherapy, B & N's Quamut says, "is the practice of enhancing health, mood, and appearance through the use of concentrated plant extracts called essential oils." The Quamut, for example, says coconut oil "supports healthy function of immune system."
There's no mention that many consider aromatherapy, in the words of a mostly uncritical Wikipedia article, "a pseudoscientific fraud." As the Skeptic's Dictionary says:
Besides personal experience, the only kind of research aromatherapists seem interested in is in reading what other aromatherapists have said or believed about plants or oils. The practitioners and salespersons of aromatherapeutic products seem singularly uninterested in scientific testing of their claims, many of which are empirical and could be easily tested. Of course, there are many aromatherapists who make non-testable claims, such as claims regarding how certain oils will affect their "subtle body," bring balance to their chakra, restore harmony to their energy flow, return one to their center, or contribute to spiritual growth. Aromatherapy is said to restore or enhance mental, emotional, physical or spiritual health. Such claims are essentially non-testable. They are part of New Age mythology and can't really engender any meaningful discussion or debate.
Quamut also has a wiki where it solicits contributions from anyone. Let's hope they're not all as bogus as this one.
