~The volume which we present in Helsinki with satis- 
faction to our coleagues from the field of photogrammetry 
and photointerpretation is starting a new library edition, 
which we hope will be continued in the coming years. Such 
a library edition in due time will allow the completion of 
an actual documentation of photogrammetrical works for all 
member — countries of ISP. This bibliography owing to its 
completion and integrated form will be an excelent supple- 
ment of the bibliographical cards issued in Enschede by 
the International Institution for Aerial Survey and Earth 
Sciences /ITC/. 
"e hope also that in a short time Photogrammetry will 
enter one of the computer informatical systems, which in a 
considerably better manner than bibliographical cards will 
cover the bibliographical demands of the users. In this 
case most actual and complete bibliographical records will 
be indispensable. 
"e expect that the reading colleagues will kindly re- 
alize the difficulties which faced the National Photogram- 
metric Societes in the preparation of the bibliographical 
material. 
We will be grateful for your constructive criticism 
concerning the bibliographical arrangement, which could 
improve the next volumes of the ISP bibliographical libra- 
ry edition. Working Group VI-5 on "Planning economy, orga- 
nization of photogrammetrical establishments, professional 
aspects" is directed by S.J.Friedman /USA/. 
The Vorking Groups have been preparing a brochure 
which will list the organizations of each member society 
and key officers. This should greatly encourange scienti- 
fio cooperation and communication between various natio- 
nal organizations.
