A catalog is presented of 414 diffuse interstellar bands (DIBs) measured between 3900 and 8100Å in this spectrum. The central wavelengths, the widths (FWHM), and the equivalent widths of nearly all of the bands are tabulated, along with the minimum uncertainties in the latter. Among the 414 bands, 135 (or 33%) were not reported in four previous, modern surveys of the DIBs in the spectra of various stars, including HD 183143. The principal result of this study is that the great majority of the bands in the catalog are very weak and fairly narrow. Typical equivalent widths amount to a few mÅ, and the bandwidths (FWHM) are most often near 0.7Å. Description: The spectra were obtained with the 3.5m telescope and the ARC echelle spectrograph (ARCES) at Apache Point Observatory. Each exposure provides nearly complete spectral coverage from about 3700 to 10000Å at a resolving power R=38000. The star's spectrum was recorded on each of three nights in 1999: May 30, May 31, and June 11.

Note (1): Note as follows: d = blend with another DIB (diffuse interstellar band); s = blend with stellar line; t = blend with telluric line; det = detector artifact; s1 = blend with stellar NI; s2 = blend with stellar NII. Note (2): Indicates more than one (isolated) stellar line interfers, typically for a broad DIB (diffuse interstellar band). The corresponding sum of the equivalent widths is given in BEW. Note (3): b = the stellar line measured is itself a blend of at least two lines.
