Start a website. Send reviews to likely outlets-not just Comics Journal and other trade publications, but mainstream ones as well. This genre of paper is quite likely to have a readership sympathetic to GNs, even if they haven t read any before. Chances are, titles that you ve known about for years will be completely unknown to the people reading your article. A lot of publishing outlets accept interviews.
Local newspapers like to feature local individuals doing interesting things.
Specialty papers or magazines are interested in interviews with people working in those specialties, or who are members of groups of interest to the venue s readership. Ask your local library to get your favorite titles, even if you have them yourself. If you re feeling particularly energetic, volunteer your time to set up a display about GNs at your local library. This is kind of a long shot unless the library is actively planning such an exhibit, but maybe you can convince them to at least consider it. Donate some GNs to your local library.
