Halcyon Days: Interviews with Classic Computer and Video Game Programmers is a digital book edited by James Hague and published in 1997. The book was originally formatted using HTML and sold via mail-order, shipped on a floppy disk by Dadgum Games for USD $20. In 2002, Halcyon Days was made freely available on the web. The book continued to be sold by Dr. Dobb's Journal, on a CD-ROM also containing Susan Lammers's Programmers at Work, until Dr. Dobb's shut down at the end of 2014. The introduction to Halcyon Days is written by John Romero who told Wired News the interviews were "like hearing messages from old gods." Halcyon Days has since become a common reference for writings on game history, including Racing the Beam (MIT Press, 2009), and Retrogame Archeology (Springer, 2016). Source: Wikipedia (en)
