A Practical Reference Library in Five Volumes — keyed from the public-domain original

Entry of the Day

Six thousand, eight hundred and forty-six entries — and each day the encyclopedia opens itself to just one of them. Come back tomorrow for the next.

Rights & ReuseThe complete text of Aiton’s Encyclopedia (1910) is in the public domain in the United States — like all works published before 1928 — and is free to read, download, quote, teach from, and reuse.
