I have a strangely deep admiration for archaic language and its usage and find that when working on period-piece writings, sources (catalogs of old books) for researching words used in the period (And how the words are used in context therein) are exceptionally helpful. Does anyone know of any more hidden-in-the-web catalogs that would be useful for finding old words in books? (kind of like Google books, but perhaps less-popular sites which don't get too much attention but are worth keeping for a rainy day.)
P.S. by "early uses of words" I refer to the periods in the English language from the 15th century to the 18th century.
Thank you very much so, any insight would be humbly appreciated.
