The Institute of Advanced Legal Studies possesses a wealth of archival and open-shelf legal materials (judicial studies, legislation, law reports) from across the former British West Indies and non-Anglophone territories. The former are mainly donated by the Colonial Office, The Commonwealth Office and independent governments, and span from early British colonisation (1600s) to the present. The latter mostly cover the 20th century to the present, although there are some historical sources.
In IALS Colonial-era materials are housed in L3 (Lower floor 3, basement) under the RES GN (reserve) and RES FOL GN (Folio, large books) classmarks.
Post-independence, Commonwealth and other Caribbean materials are housed on the IALS library open shelves mainly under the GN class mark.
Again, this guide is cursory rather than comprehensive so please consult the catalogue for sources that are not detailed below.
