Hi,
My name is Andrew and I'm new here. This forum is great and I decided that I must register.
Looking for some books for some time but in my country are very hard to find, even impossible.

Jane's World Sailplanes and Motor Gliders - Coates, Andrew (1978).
Gliders and Sailplanes of the World. Shepperton - Hardy, Michael (1982).
Jane's Encyclopedia of Aviation - Taylor, Michael J. H. (1989).
Airlife's General Aviation - Simpson, R. W. (1995).

If anyone has it in pdf and other digitally format I would be very grateful.
Thanks in advance.
I hope I have not posted in the wrong place.
