CINDA 79 supplement. 1 October 1979

This issue of CINDA indexes, for a given work, not only its bibliographic references but also its numerical data stored in computer libraries, which are available from the four regional neutron data centres. Since July 1970 the exchange of experimental neutron data between the U.S. National Nuclear Data Center, the NEA Data Bank, the USSR Centr po Jadernym Dannym and the IAEA Nuclear Data Section has been structured in the EXFOR exchange system, so that data entered at one centre are made available to the other three. Similarly, evaluated neutron data libraries or parts of them are generally available from the same four centres. Whereas in earlier issues of CINDA the availability of data sets from the data centres was publicized by a simple tag (+) at the right-hand margin under the heading ''Data'', it was decided to include more information about these data by adding a ''data-index line'' below the bibliographic reference(s) of a given work. Users of CINDA 79 will find such data-index lines for the experimental neutron data exchanged under the EXFOR agreement, as well as index lines referring to evaluated neutron data Libraries which are generally available
