Read a short official-source brief, decide the GS paper it maps to, and file only what earns a revision slot. UPSC Shelf current affairs stays a public catalog — your private library holds what you annotate.
Four steps that stay sustainable
Scan official sources
PIB, ministry releases, budget / survey extracts, and quality editorials — not every viral thread.
Map to GS paper
Tag each note as Prelims fact vs Mains analysis (GS 2/3 especially).
File or discard
Only keep what you will revise. Hoarding PDFs without a return path wastes time.
Weekly revision pass
Schedule a Planner block; generate a short quiz from the month’s saved briefs.
