The Baker Street Irregulars Trust

The Baker Street Irregulars Trust collects, preserves, and makes accessible the historical records of the Baker Street Irregulars and the world of Sherlock Holmes. The Trust maintains the BSI Archive at the Lilly Library at Indiana University — open to scholars and the public alike — and supports ongoing projects including the Oral History Project, which captures the voices and memories of BSI members across generations.
The BSI Archive

Ninety years of history, preserved for the next generation.

The BSI Archive — now housed at the Lilly Library at Indiana University — holds the collected records of the Baker Street Irregulars since the organization’s founding in 1934. The collection includes correspondence, photographs, dinner programs, memorabilia, and the personal papers of BSI members. A detailed finding aid is available through the Lilly Library, and the archive is open to any qualified scholar.

Oral History

Voices of the Irregulars

Since 2006, the BSI Oral History Project has recorded more than 250 interviews with BSI members — their memories, their friendships, and their lives in the world of Sherlock Holmes.

History
