So far, only the 1980 series up through issue 58 are available (plus annuals, specials, etc. from that era). #59 began reprinting previous stories, so I'll hold off from that. The next series started in '84 (again as "The New Teen Titans") and ran about 130 issues. I'll get those up at some point followed by the 50 issue "The Titans" series and the current "Teen Titans" one.
