TechWhirl (TECHWR-L) is a resource for technical writing and technical communications professionals of all experience levels and in all industries to share their experiences and acquire information.
For two decades, technical communicators have turned to TechWhirl to ask and answer questions about the always-changing world of technical communications, such as tools, skills, career paths, methodologies, and emerging industries. The TechWhirl Archives and magazine, created for, by and about technical writers, offer a wealth of knowledge to everyone with an interest in any aspect of technical communications.
For a list of the journals relevant to technical communication and
information design, I humbly recommend checking Appendix A of my book
Dynamics in Document Design: Creating Texts for Readers (pp. 498-501). It
presents over 40 journals of note and offers mission statements as well as
addresses for subscribing. I also present a photo collage of all the covers
of these journals on pp. 98-99. You might also check the Association of
Teachers of Technical Writing (ATTW) Web Site; it has many resources you
might find of use. It's URL is: http://english.ttu.edu/ATTW/
