I decided I'd got far too many unread books loitering around the place so I went through about 100 of them today. Many I don't think I will ever read even though I obviously thought I would when I bought them. The majority are second hand and cost me very little fortunately as if I buy a new book I will always at least attempt to read it even if I give up after 50 pages. I generally read at least 50 pages before coming to a decision. If a book hasn't grabbed me by that stage I won't usually persevere unless I have to write a review of it.
Having gone through them I've listed them all for sale on eBay and Amazon. And sold one within about 10 minutes - so that was a good start! If they don't sell within a few months they can go to a charity shop. If I didn't get ruthless with them I'd need a new house to put just the books in! The upside of the clear out is that I came across about a dozen which I'd forgotten I had and they've got themselves higher up the to read pile.
