The data are here . I picked them up on the NCAR ftp site and rewrote it to the stunningly effective (shrinking 45MB of original "anomalies_landonly" ASCII file into a 3MB file, achieving meanwhile direct-access capacity) CUF format by Senya Basin. Since the NCAR documentation was not terribly clear (and with obvious mistakes sometimes), I well could mess it up somewhere along the way (although I doubt it!). Anyways, if something looks suspicious, send me an email, or check out yourself the original NCAR source directory.
Note: There two datasets of climatology (by NCAR and by Jones) in the same NCAR directory. I put only Jones' climatology here.
Below I dump all relevant documentation I could find on the NCAR ftp site.

The anomalies are not anomalies from a climatology grid. They are anomalies from a period mean, station by station. Although, Jones tries to pick a base period, it was just not available for each station, so what was available was used. Then, the grid of anomalies was analyzed with area-weighting and smoothing. If one wants a grid of temperatures rather than anomalies, we tell users to just add our climate grid. Keep in mind that Jones' anomalies are air temp- eratures over land and sea surface temperatures over water, so the resulting grid of temperatures is not air temperatures the world over. They will be close in many areas, but where cold currents they will be off, etc. Sea surface temperatures were apparently chosen for the advantages of con- sistency and continuity, and to avoid inherent problems in ship reports. Also, be aware that if you are using the latest anomaly grids, they 2.5 degrees off in spacing from the climate grids. We do have hardcopy documentation about the hemispheric climatology grids, but we really do not have any more documentation than this about the anomalies. If you want more detail, you may try to contact Phil Jones, F028@CPCMA.EAST-ANGLIA.AC.UK or Mike Salmon, email@example.com ..............
