(2) Articles pubhshed m the open hterature. (3) Articles from the bimonthly Deep Space Network rDSN) Progress Report (42- senes). Each collectiOn of articles In this class of publicatiOn begInmng With 42-20 presents a periodical survey of current accomphshments by the Deep Space Net work Formerly, each collectIOn of articles was pubhshed as a separate volume of Techmcal Report 32-1526 (4) Techmcal Reports (32-senes), In which the m(ormatlOn IS complete for a speCific accomphshment and IS Intended for a Wide audience (5) Techmcal Memorandums (33-senes), In which the Information IS complete for a speCific accomphshment but IS Intended for a llffilted audience to satisfy umque reqUirements. (6) Special PublicatIOns (43-senes), m which the mformatlOn IS complete for a speCific accomplishment and IS presented m a special format to emphaSize ItS umque character and directiOn. Effective January 1977, the "JPL Publication" replaced the Technical Report, Technical Memorandum, and SpeCial PublicatIOn. However, the dIscontmued classes may stIll appear In future Issues of the Blbhography If succeeding volumes or reViSions are published In their former senes. The pubhcatlOns are Indexed by (1) author, (2) subject, and (3) pubhcatIon type and number A deSCriptive entry appears under the name of each author of each publication, an abstract IS Included With the entry for the pnmary (first-listed) author JPL personnel can obtam loan copies of formal documents cited from the JPL Library.
