Such documentation should be made available for free as ti pay and wait for such documents makes it uses questionable for people in the south. And therefore such papers become academic and of little use for the intended users namely practinioners that need it now now and not months from now with payment problems etc. Therefore you have to try to make a system that could be utilised by practioners working in the south to make use of such documents.

Also the information is a little to small to see if it is worth the trouble and the Euor 9. I am at present in Afghansitan so you could imagine how difficult it is to organise buying such documents while being interested in the experience as we are heavyly involved with community hand pumps
