The jQuery Library for SharePoint Web Services is a jQuery library which abstracts SharePoint's Web Services and makes them easier to use. It also includes functions which use the various Web Service operations to provide more useful (and cool) capabilities.
SharePoint's Web Services allow you to interact directly with SharePoint objects such as lists and webs without deploying any server-side code. The various Web Service operations can be built together into more full-featured functionality that can provide real value to SharePoint users.
The jQuery Library for SharePoint Web Services includes not only jQuery "wrappers" for the most commonly used Web Services and their operations, but also value-added functions that let you add functionality to forms and pages with very little work.
