摘要:Library management systems were some of the first systems to take advantage of the web in the late 1990s1,as a means of providing easier access to library catalogues and opening up the collections. As the webdeveloped through the first decade of the 21st century, though, it became apparent that the web interfaces usedfor the OPAC were limited in their capacity to present the riches of our catalogues to their full extent. Existinginterfaces were capable of being tweaked, to considerable degree in some cases, but lacked the flexibility thatwas evident on other websites, and particularly other websites offering information services2. The librarycatalogue was no longer the primary place to discover information, but one of a number of sources, and OPACinterfaces have needed to rise to this challenge.
