It was only after the restoration of the Society of Jesus the archives began to take shape. In 1934 correspondences and diaries were stored at Trichy. The earliest and most substantial materials of the archives are related to the Jesuit Bishops Alexis Canoz, Jean Marie Barthe, Augustin Faisandier and other Jesuit bishops like Jean Peter Leonard and Tiburtius Roche. Till 1936 the documents preserved in the Cathedral residence of Jesuits at Tiruchirappalli were brought to Sacred Heart College(SHC), Shembaganur. This was because the Society of Jesus was handing over the Diocese of Trichinopoly to the local clergy. Hence the province had the responsibility of preserving the documents pertaining to the Jesuits separately. This they did in Shembaganur.

SHC started in 1895 and it housed the Jesuit scholastics, doing their spiritual formation (Novitiate), study of humanities (Juniorate), and Philosophy for the Madurai Mission. From 1937 onwards, one of the philosophy faculty, Fr. Gathier was in charge of the Archives. The first official archivist, Fr. Augustine Sauliere, the typist, Mr. Anthony Doss, and Fr. John Pujo, did a tremendous job in the Archives. From 1997 till 2005 many Jesuits took turns in serving at the Archives. From 2006 onwards the systematic work of scanning and computerizing the archival materials started by Fr. Joseph Antonysamy SJ. The particular portion of the building which houses the archives was constructed in 1924. The total carpet area of the archives is about 8300 sq feet.
