Most dictionaries are prescriptive: they tell you how a word should be used. The OED is descriptive: it tells you how a word has been used throughout history.
If you open a standard dictionary for the word "nice," it might say: Adjective. Pleasant; agreeable.
If you open the OED, you will discover that "nice" has had a wildly chaotic life. In the 14th century, it meant "foolish" or "stupid." In the 15th century, it meant "wanton" or "lustful." Later, it meant "precise" (as in "a nice distinction"). Only recently did it settle into its modern meaning of "pleasant." oxford english dictionary.pdf

When Murray finally went to thank him in person, he discovered that Dr. Minor was an inmate at Broadmoor Criminal Lunatic Asylum, imprisoned for murder. Minor, suffering from delusions, had found solace and purpose in the ordered world of lexicography. His story remains one of the most poignant tales in literary history, proving that the OED was a collaborative effort built on the contributions of the eccentric, the obsessed, and the brilliant. Pleasant; agreeable
Oxford University Press publishes an official app for mobile devices. While it requires a subscription (usually around $10–$30/year), it is searchable, offline-capable, and far more functional than any pirated PDF.
OUP publishes a Compact Edition of the OED (1987 reprint). It fits the entire 20-volume text onto 2 huge pages per original page, using a magnifying lens. You can buy a used copy for $200–$400. While not a PDF, it is a physical offline archive.
