वो search engine जो खगोलशास्त्री असल में इस्तेमाल करते हैं — लाखों astronomy और physics पेपर्स। ज्यादातर records arXiv या publisher के full text से लिंक होते हैं जिन्हें आप import कर सकते हैं।

Working astronomers use ADS instead of a general search engine because it indexes astronomy and physics literature back to the 19th century and links papers to their citations and data in ways broader tools don't. A notebook tracking how a finding got cited and challenged over time benefits from ADS's citation network view. Most records route to arXiv or a publisher, so full-text access still depends on where the paper originally landed.
