Is there any chance you could separate out just the Electronics related ones including data books, box them and post them?
I'm in Sydney, would pay postage.
Edit to add:
Speaking of giving away a box of books...
I recently saved a pile of Chinese language books from being binned. Can't stand to see books destroyed.
I'm told by a Chinese neighbor of mine, that they are a wide range of topics, from famous Chinese historical works, through poetry, well-known literature, to kung fu novels.
Pics of them all here:
http://everist.org/pics/books/I'm hoping to find someone who'd appreciate these and enjoy reading them. Obviously I can't read Chinese and never will be able to, much as I wish I could. (And btw, now I know the meaning of the sequence ordering pictorgrams and realise I arranged volumes out of order in the photos.)
Anyway, these are free to a good home. Preferably pickup in Sydney Sth area, but I could post them if necessary. All in one lot, no selections.
The only condition is you have to convince me you can read Chinese, and will cherish and preserve them. No cutting them apart to scan them then binning the remnants. People who do that are barbarians.
