"It's raining, it's pouring, the old man is snoring!" "The itsy, bitsy spider crawled up the waterspout, down came the rain and washed the spider out. Out came the sun and dried up all the rain, and the itsy, bitsy spider went up the spout again." What do children's nursery rhymes have to do with the school library? The author begins by telling a story about her present school library assistant. Eight years ago, she was a volunteer parent. She loves to tell the story of the sunny, beautiful day she walked into the library and stopped at the door to observe the author running frantically up and down the rows in the library computer lab covering the computers with sheets of plastic. Not knowing what was happening, she stood and watched only to be splattered with water dripping from the ceiling! She said she looked up and couldn't figure out why it was raining inside when it was a beautiful day outside! They both laugh over the story now; however, that day it was not a laughing matter. Unfortunately, eight years later, water still drips from their ceiling on rainy days. In this article, the author shares the things she learned from this situation. She says one should: (1) realize even a new building has flaws; (2) be aware of potential problems during new construction; (3) keep administrators current on the situation; (4) keep detailed notes on leaks and damage; (5) be friendly towards custodial staff; (6) keep plenty of plastic trash bags and pieces of plastic handy to cover materials, equipment, and furniture; (7) be aware of mold growth and what it looks like; and (8) check out the U.S. Environmental Protection Agency site for more information on mold, mold damage and remedies. Above all, make sure to keep the situation in perspective. Laughter can help!
