IV. - Computerized bibliog raphic system 
In accordance to the last Congress resolutions the recognition 
of computerized bibliographic systems should be performed. 
In Europe, European Space Agency has the space documentation 
service ESA RECON, which offers a high performance and high 
capacity computerized information retrieval system. Their opera 
tion is based upon an interactive on line dialogue. Remote 
terminals connected to a central computer are used for biblio 
graphic citation retrieval. This system contains 18 files cove 
ring among others NASA file based on Scientific and Technical 
Aerospace Reports /STAR/ and International Aerospace Abstracts 
/IAA/ as well as NTIS file /National Technical Information 
Service/, and PASCAL file /France/ both covering multidiscipli 
nary science and technology. 
Above mentioned systems cover only one part of the activity of 
our Society, so the necessary efforts should be taken to in 
clude photogrammetrie bibliography to the one of the existing 
systems. 
We are expecting information from our reporters in USA and 
Canada where similar systems are existing. 
According to the last ne\is received from Geo Abstracts, they 
will produce the bibliography in a fully machine readable form 
by 1980 .
