A survey of ultracompact (UC) H II regions has been carried out by searching for 6.669-GHz methanol maser emission from a sample of 535 IRAS-selected candidates. A total of 201 candidates exhibit methanol emission. These sources have been used, in conjunction with previously identified UC H II regions, to provide a base for further studies of such regions. Estimates of distances have indicated tha...
