You may realize by now, but there is no "Lost City" series. It is just a lot of modules feature a lost city, and they often put that in the title, and many of my favorite modules fall into this category. I also like the old B4 The Lost City and I1 Dwellers of the Forbidden City, both of which have some set encounter areas and larger, less detailed sandbox areas. Don't know if either are commonly available now.
Vaguely related: Does anyone know if the Steve Jackson games site is still selling the Runequest reprints. I got a lot of old stuff from them, including Griffin Mountain and Pavis and the Big Rubble, but that was a few years ago. You guys make me yearn to try and run my True 20 Glorantha campaign again.
