I have spent several hours going through one box of many resources accumulated over a lifetime of teaching and administration. One box, taken from a bedroom and a shedful of boxes. This particular box was a collection of carefully collected, collated, organized and filed newspaper articles, commentaries, editorials and so on. Each piece had been careully cut and trimmed, pasted onto a piece of paper as a background and labelled with date and the name of the publication to produce a photocopiable master. Some were accompanied by ditto masters, some by OHP transparencies. Thousands of hours of work, all on its way to the recycling bin.
