In 2003, the Institute started informatizing its library.Until the 1950s, the IHGRGS was the main producer and diffuser of historical knowledge in the state, even more than the Federal University of Rio Grande do Sul (UFRGS). In the 1930s and 1940s, with the celebration of the Ragamuffin War centennial and the historical congresses of Rio Grande do Sul, the IHGRGS reached its peak. However, from the mid-1940s on, there was a division between members who defended a renewal of the historiographical model and those who remained faithful to a more political and military approach. From then on, the Institute lost its hegemony in the local historical production.The Revista do Instituto Histórico e Geográfico do Rio Grande do Sul was published quarterly and uninterruptedly from 1921 to 1950, appearing again in 1975; currently it is part of the UFRGS academic journal system and is published every six months.
