In her biography about her horticulturalist father, Jonathan Baldwin Turner, Mary Turner Carriel wrote the following of Turner's quest to fence prairies; words that may also serve as an allegory for present-day libraries: What he could have done to tempt the pioneer from his home in the East to settle upon the fertile lands in the West. The first problem was to get something for fences. It must be "horse-high, bull-strong, and pig-tight." Libraries have a similar quest today: to tempt patrons from the large number of freely available resources on the Internet to the carefully selected and organized electronic and physical resources available through the library. And, as with fences that need to keep in a wide variety of livestock, our library systems must meet the needs of all types of users in an efficient and effective way, especially with regard to the discovery system.
