Editorial Policy & Astrological Standards

Summary: Astrolibrary prioritizes technical accuracy and ethical integrity. We use astronomical data from NASA’s JPL ephemeris and the Swiss Ephemeris for astrological calculations. We don’t offer sun-sign horoscopes because they lack individual meaning. Instead, we provide personalized transits reports. And we focus on self-discovery and life enhancement, rather than deterministic predictions.

At Astrolibrary, here’s what we do to make sure we provide the most accurate astrology resources. We adhere to the following technical and ethical standards.

1. AstroLibrary’s Astronomical Accuracy Comes From NASA’s Ephemeris

Astrology is only as good as the math behind it.

• To ensure every our astrology calendars and planetary positions are accurate, we use NASA’s Jet Propulsion Laboratory’s most accurate ephemeris, which is the JPL DE440, not DE441.
• To ensure our astrological charts and reports are accurate to the second, including house cusps, transits, and precise geographical coordinates, we use the Swiss Ephemeris (which is also derived from NASA’s JPL, but it uses the JPL DE441, although we’ve tested it against the data from JPL DE440 and it matches for astrological purposes since we only need accuracy to the second of arc.

2. AstroLibrary’s Stance on Sun-Sign Horoscopes

Even though “sun-sign horoscopes” are popular in mainstream astrology, we do not offer “sun-sign horoscopes” at AstroLibrary because we believe those generic forecasts do not represent real astrology. A sun-sign horoscope ignores 90% of a person’s unique birth chart. It treats one-twelfth of the world’s population as having the same daily experience, which is practically impossible, and astrologically and mathematically wrong.

Our Alternative To Sun-Sign Horoscopes: We prioritize Personal Transits Reports. Our daily reports use your specific date, time, and place of birth to calculate how current planetary movements interact with your unique natal placements. This provides a personalized map of energy rather than a generic guess.

3. Ethical Interpretations & Personal Agency

AstroLibrary’s policy regarding interpretations and predictions is that we want to describe the “weather” of your life so you can take advantage of it. We do not believe in a deterministic or “fated” approach that removes your free will.

• Potential Energies: We describe potential energies, strengths, and challenges present in a birth chart or transit to help you spot opportunities for growth or prepare for potential friction.
• Non-Deterministic Advice: We do not make definitive predictions about health, death, legal matters, or specific life events. We believe in human agency and the complexity of the psyche. However, the section of our site that has a library of ancient astrological books may include historical texts that contain such predictions, but they are presented as historical artifacts rather than current advice.

4. Integrity of Content

All content and interpretations found on AstroLibrary are written or vetted by experienced professional astrologers. We value the historical tradition of astrology and we strive to present it in a way that is practical and, above all, astrologically accurate.
