This is highly selective but always-expanding list of critical DH infrastructure, in no particular order:

• DH Answers. Forum for asking and answering questions, on everything from minute technical particulars to big picture.
• DH Now. Daily broadsheet curated by rotating editors at large.
• ADHO. Main professional umbrella organization for DH practitioners.
  • Association of Computers and the Humanities. The largest North American ADHO membership organization.
• Digital Humanities Quarterly. Peer-reviewed journal published by ADHO.
• Digital Humanities. The annual conference sponsored by the ADHO membership organizations, this year at University of Nebraska-Lincoln.
• NEH’s Office of Digital Humanities. Funding programs, but also reports from past projects.
