I can't quiet down. That's why I work at the part of the Library of Congress where I can (and do) make the most noise😉😋 #recordedsound

Better late than never! The 2nd week of April 2026 will mark the start of my 28th year at LOC! I still can't believe I get paid to do this job ❤️ #Librarian #RecordedSound

In the history of #RecordedSound, the very first were #LéonScott ’s #phonautographs of 1857-61, which could record soundwavesforms but not play them back. At least that was what people thought, until science learned how to change the phonautographs back into sound again.

In case anyone wonders where I work and what it looks like inside 😉 #LibraryLife #RecordedSound
