Radio Pulsar Timing
  The motivation for radio pulsar timing and its basic principles are reviewed. Present and future radio timing techniques and hardware are summarised and compared. The array of present timing programmes and their scientific goals are collated and described. Recent results and future prospects are discussed, with emphasis on multi-wavelength techniques where appropriate. Timing of radio pulsars at other wavelengths is summarised along with the provision of contemporary ephemerides for timing and searches at other wavelengths.
