The Library of Congress holds literally millions of items, many of which have been digitised. But how to approach such a huge collection? LOC Serendipity is one amazing answer: surface content at random, and allow people to follow whatever rabbit holes they find interesting.
Even just the randomly selected titles are great, like some sort of Oblique Strategies prompt:
Miscellaneous studies in prose
Politics and pen pictures at home and abroad
Virginia in the making of Illinois
Interest tables used by the Mutual life insurance company of New York for the calculation of interest and prices of stocks and bonds for investment
La dame aux perles
Elements of logick
Elisa von der Recke
The present world situation
Military character, habit, deportment, courtesy and discipline
Memorial of Mrs. Agnes Renton
Ballot box and battle field
I’m particularly fond of the “Infinite 78RPM Records” section, which throws up a never-ending stream of old, public-domain records – mostly ’20s and ’30s jazz but also some scratchy gospel, bluegrass, and folk and ancient stand-up comedy.
