AAAARG.ORG  

A huge library of texts old and new, access by free login. Sample issues with an architectural bent include quasi-architecture and post-critical architecture.
“AAAARG is a conversation platform – at different times it performs as a school, or a reading group, or a journal… AAAARG was created with the intention of developing critical discourse outside of an institutional framework. But rather than thinking of it like a new building, imagine scaffolding that attaches onto existing buildings and creates new architectures between them.”

bracket  

[bracket] is an annual publication documenting issues overlooked yet central to our cultural milieu that have evolved out of the new disciplinary territory at the intersection of architecture, landscape, urbanism and, now, the internet. It is no coincidence that the professional term architect can also now refer to information architects, and that the word community can also now refer to an online community. [bracket] is a publishing platform for ideas charting the complex overlap of the sphere of architecture and online social spheres.

Cloud Cuckoo Land  

Occasional german architectural journal with a new theme each year. Abstracts in English but the body of the essays is usually in german.

Design Philosophy Papers  

The current issue only is freely available online.

“Design Philosophy Papers (DPP) comes from a longstanding desire to gain greater recognition for the study of design by the intellectual community at large, as well as our frustration with the market-driven conservatism of design publishing. It aims to break away from the idea of design as a specialist interest, as well as rejecting the simplistic and debased way design arrives before the public via both old and new media — frequently merely as style or technics. It also comes with a passion to communicate, share and argue for a much, much greater general recognition of importance of design and ‘the designed’ as managed and unwitting agents of force and power.”

Friends of Kebyar  

An occasional journal of Organic Architecture.

Interstices

Log Journal  

A carefully crafted compendium of essays, conversations (interviews), and short observations on contemporary buildings and trends, Log eschews the visual culture of the moment in favor of determined forays into the critical and cultural implications of the discipline.

Modernism/modernity  

Scholarly journal at Project Muse (Johns Hopkins University). It used to be free… but now it isn’t. Oh well, I’ll stay dumb.
