Peter, et al,
Yes, I know about "proper" archival storage, but it was said tongue in cheek....
I've tried the ebook thing...no good for me...when I do use the library I'm usually researching an issue/ problem and end up with a few books open at a time to compare info..can't do that on a ipad.
I did TRY, when I came o'seas to just bring a few books with me, one's that I thought would be used....like my wife's clothes when she packs...only 50% were actually used and I ended up purchasing copies of books I knew were back in storage in Oz.....
I'm thinking...go through and sort the active interest books, then the $$$ collectables and the "series" books (Like many others I just hate seeing Vol 2 (of a 5 Vol series) just sitting alone on the shelf - it must reunited with it's mates...)
The rest (sigh) may have to go like they do at Hay on Wye (The book town) sell by the bag (or per Kg) or by the shelf length ( so much per foot)...Hmm I could always rip the spines off and glue them to some customwood sell as a "safe/ secure storage front!!! (Only joking, but it IS done in Hay on Wye)
(Let's not talk about divorces - been there tried that.....)
