While it is fine to download this PDF for study or analysis of old buildings, you must not use it for designing a new structure.
The Bureau of Indian Standards (BIS) revised the code to IS 456:2000 for critical reasons:
Warning: If a structural engineer submits a design based on the 1978 code today, it will be rejected by municipal authorities for building plan approval, and it may lead to legal liabilities.
Because countless existing structures were built using that code, and because some old textbooks still reference it. Also, keyword habits from older engineers persist.
BIS maintains a library in New Delhi and regional offices. You can visit, get a day pass, and photocopy relevant clauses of IS 456:1978 for your personal reference (subject to fair use).
Legally, no. But many universities have a relaxed attitude for educational use. However, you risk downloading malware. Instead, ask your college library for a licensed copy.

The search for “is 456 code 1978 free download pdf new” is understandable. Every civil engineer respects the legacy of this standard. However, free and legal full downloads do not exist. Your best paths forward are:
Remember: Using a pirated 1978 code not only disrespects the intellectual property of BIS but also risks compromising your project with incomplete or corrupted data. The 1978 code is a historical masterpiece – treat it with the respect it deserves by obtaining it legitimately.
If you need the most up-to-date concrete design requirements, leave the 1978 edition on the history shelf and adopt IS 456:2023 for all new work. Your buildings will be safer, legally compliant, and built for the 21st century.
IS 456:1978 is an outdated edition of the Indian concrete code and has been superseded by IS 456:2000. Official BIS standards are generally not available as free downloads; obtaining the current, authoritative standard should be done through BIS or authorized sources to ensure legal compliance and accurate, safe practice.

The document you are asking about, IS 456:1978, is the third revision of the Indian Standard Code of Practice for Plain and Reinforced Concrete. While it is no longer the "new" or current version—having been replaced by IS 456:2000—it remains a document of significant historical and academic value for structural engineers. Is it "New" or Still Free?
Version Status: IS 456:1978 is outdated. The current governing code in India is IS 456:2000, which includes critical updates like Amendment 6 (April 2024).
Free Access: You can find the 1978 version and its companion design aids (SP 16) for free via public archives. For example, the Internet Archive hosts the SP 16: Design Aids for IS 456:1978.
Purpose Today: Most modern construction projects in India must use the 2000 version. The 1978 version is typically used only for academic comparison or when retrofitting structures built during that era. Historical Significance of IS 456:1978
The 1978 code was a landmark because it transitioned Indian engineering from the Working Stress Method (WSM) toward the Limit State Design (LSD) philosophy. IS 456:1978 (Old) IS 456:2000 (Current) Primary Method Primarily Working Stress Method Limit State Design (LSD) Safety Factors Single factor of safety for materials Partial safety factors for both loads and materials Durability General recommendations only Exposure-based (Mild to Extreme) Concrete Grades Limited clarity on higher grades Clearly defines M10 up to M80 Key Resources for Engineers
