| Abstract: | We summarize the progress in identifying and observational study of extremely metal-deficient (XMD) gas-rich galaxies (BCGs, dIr and LSBDs). Due to volume limitation only the following issues are addressed: sample creation, some statistical data, Colour-Magnitude Diagrams (CMD) and ages, the case of SBS 0335–052 system, and probable evolution paths of various XMD objects. This revised version was published online in August 2006 with corrections to the Cover Date. |
