摘要:The nut. The bolt. When you go to the hard-ware store with a bolt in hand, you probably feel pretty confident that you’ll be able to find the nut you need to tighten that bolt. When I hand over my bolt to my local Rex Ace Hardware man, he strides down a nearby aisle and within seconds, I’ve got my bolt’s mate. It screws on perfectly. Do I care who made the bolt or the nut? I do not. This is because nuts and bolts have standard on sizes and threads. Any quar-ter inch nut will screw onto any quarter inch bolt. That’s how it should work with the nuts and bolts of library software – the integrated library system (ILS). But that isn’t how it works at all. For various reasons, our library systems have evolved into Winchester Mystery Houses that require all sorts of special, and often expensive, adaptations to bolt anything onto them.
