The 6C survey of radio sources - V. The zones 6C-Va (48<delta<68, 01h34m<alpha<06h14m) and 6C-VB (48<delta<68, 17h16m<alpha<20h24m).
This paper complements Paper III of the series on the 6C survey of radio sources, presenting the remaining parts of the observations of the strip 48^deg^<δ<68^deg^ which extend the coverage into the regions of lower Galactic latitude at those declinations. The observations made and the data reduction methods and other conventions adopted for the strip are described in that paper; details will not be repeated except where they differ or require comment. The data here presented consist of 92 pages of maps covering two regions: 48^deg^<δ<68^deg^, 01^h^34^m^<α<06^h^14^m^ and 48^deg^<δ<68^deg^, 17^h^16^m^<α<20^h^24^m^, together with a corresponding list of 3458 sources. Both regions have some right ascension overlap with the zone 48^deg^<δ<68^deg^, 05^h^25^m^ <α<18^h^17^m^ covered in Paper III, so that 396 sources have alternative entries-in that list. Furthermore, the declination range 67^deg^<δ<68^deg^ is also covered in Paper IV of this series.
