The IABSE Congress Reports collect the papers presented at the quadrennial IABSE Congresses. These have a broad coverage of themes and are of a high technical-scientific standard. First published in 1932, contributions may be in either in English, German or French until 1992. After 2000 the quadrennial IABSE Congresses paused and continued in 2008.
The Congress Reports from 1932-1996 are available for free online in the IABSE Publication Archive.
