It always annoyed me; always struck me as a pernicious form of vandalism. I valued books because they were an important part of my life and I possessed so few of my own. And besides, why should I care what strangers thought about the books I'd chosen to read? Their jotted egoblurts annoyingly snagged my attention, and were never interesting, polarised between so true! and utter rubbish! Accumulating my own library, it never occurred to me to jot my own thoughts in the books I owned. Even when I had a regular gig reviewing for Interzone magazine, I wrote notes on sheets of scrap paper as I went along, keyed to page and line, rather than scribble in the margins of review copies. So reading this excellent article about author's libraries and the value of annotation, has given me pause for thought. Can it be true that all this time I've been denying posterity the opportunity to peer into my thoughts? Why, I haven't even signed any of the copies of my own books that I keep on my ego shelves . . .
