The Journal of Object Technology
A free online scholarly journal that covers any sort of object-oriented software and technology with emphasis on programming languages. It was founded in in 2002 by the ETH university in Switzerland in response to SIGS Publications stopping issuing the Journal of Object-Oriented Programming and Smalltalk Report et al, leaving C++ as the only o-o language that had a regularly published journal associated with it.
The Journal of Object Technology (JOT) is published fairly irregularily about 4 to 8 times a year, it is available in both HTML and PDF format, but can only be downloaded as individual articles rather than whole issues.
