Sondheim's Lost Treasures: Broadway Legend's Secret Archives Saved from Flames

Mia Reynolds, 6/26/2025Broadway's creative legacy shines with the Library of Congress's acquisition of Stephen Sondheim's remarkable collection. Featuring 5,000 items, including lyric sketches and personal notes, this archive offers an intimate view into the mind of a musical genius, preserved in the wake of a near-catastrophic fire.

What makes this collection extraordinary isn't just its size — though 5,000 items is nothing to sneeze at. It's the intimate glimpse into the creative mind of musical theater's most celebrated composer. Coffee stains mark midnight inspiration. Margin notes reveal roads not taken. Each piece tells a story beyond the music itself.

Mark Horowitz, the Library's Senior Music Specialist, practically glows when discussing these artifacts. "It's staggering," he says, and there's something in his voice that suggests he's still processing the magnitude of it all. The collection reveals Sondheim's relentless pursuit of perfection — a creative spirit that never quite settled for "good enough."

Some of the most fascinating pieces are the might-have-beens. There's an unused reprise of "Side by Side by Side" from "Company" tucked away in one folder. Another holds variations of "I'm Still Here" from "Follies" — specially crafted for Barbra Streisand, though they never made it to her legendary voice.

Then there's the wickedly clever workbook for "Sweeney Todd." Forty pages of lyric sketches for "A Little Priest" contain more than 150 potential victims scribbled in the margins. That deliciously memorable line about the oily politician served with a doily? It emerged from this creative chaos, proving that sometimes the best art comes from exhaustive exploration.

The collection's survival story reads like a thriller. When fire tore through Sondheim's office in '95, these papers should have been reduced to ash. Some still bear scorch marks — battle scars that only add to their mystique. "There's absolutely no reason why the collection should not have gone up in flames," Horowitz reflects, still amazed by their miraculous preservation.

What sets this acquisition apart is the personal connection. Horowitz, who's spent 34 years processing collections, finds this one different. "For large collections, I tend to feel the ghost of that person over my shoulder," he explains. "But with Sondheim... it's the first time I'm processing a collection of someone who I really knew."

The evolution of Sondheim's process becomes clear through the physical volume of materials. Early shows might fill three or four boxes. Later works sprawl across eight or nine. Was it increasing complexity? Growing meticulousness? Perhaps both — a master craftsman becoming ever more devoted to his art.

Hidden among the grand works is an unexpected gem: a commissioned birthday song for a public TV contest winner's mother. Even Broadway giants, it seems, occasionally wrote simply to make someone smile.

Starting July 1, anyone over 16 with proper ID can access these materials at the Library of Congress. There, alongside collections from Neil Simon, Bob Fosse, and Gwen Verdon, Sondheim's creative legacy will continue inspiring future generations of theater makers. In an age of digital everything, there's something profound about being able to touch the paper where genius first took shape.

Broadway's creative legacy just found a permanent home, and the timing couldn't be more perfect. The Library of Congress has acquired Stephen Sondheim's life work — a collection that nearly vanished in flames back in 1995. Now, as we approach mid-2025, these irreplaceable treasures are finally accessible to the public.What makes this collection extraordinary isn't just its size — though 5,000 items is nothing to sneeze at.
