The Journal of Space Syntax ran from 2010-2017. It published a large number of high quality academic papers that reported findings from cutting edge research into space, society and the design of the built environment as they relate to the discipline of space syntax. Its articles are freely accessible via the Portico preservation archive, with the kind financial support of UCL Library.
UCL Eprints provides open access to a large number of academic research papers.
Various presentations by Space Syntax Limited staff members are available for viewing and downloading through SlideBoom.
