Update on HI data collection from GBT, Parkes and Arecibo telescopes for
  the Cosmic Flows project
  Cosmic Flows is an international multi-element project with the goal to map
motions of galaxies in the Local Universe. Kinematic information from
observations in the radio HI line and photometry at optical or near-infrared
bands are acquired to derive the large majority of distances that are obtained
through the luminosity-linewidth or Tully-Fisher relation. This paper gathers
additional observational radio data, frequently unpublished, retrieved from the
archives of Green Bank, Parkes and Arecibo telescopes. Extracted HI profiles
are consistently processed to produce linewidth measurements. Our current
"All-Digital HI Catalog" contains a total of 20,343 HI spectra for 17,738
galaxies with 14,802 galaxies with accurate linewidth measurement useful for
Tully-Fisher galaxy distances. This addition of 4,117 new measurements
represents an augmentation of 34\% compared to our last release.
