Sierra uses a particular Load Table to determine how bibliographic records are overlaid when new records loaded via Remote Search (i.e., downloaded from another library catalogue using Z39.50)

According to Sierra's documentation the default Load Table is "m2btab.b", but Innovative can configure Sierra to use another one if desired.

We have found that certain projects call for different Load Tables because different sets of fields should be retained, discarded, or inserted. It is possible to change to a different Load Table for remote search temporarily (or modify the current Load Table), but that would affect all cataloguers for the duration of the project.

Much more powerful results could be obtained if users were empowered to select between one or more pre-determined "remote search" Load Tables. In this way, the the most appropriate Load Table for the task at hand could be selected without need to edit the one in use or ask Innovative to change configuration on our behalf. From a user interface perspective, this could be accomplished in a manner similar to the workflow for selecting new record templates (i.e., allowing users to select a particular Load Table for Z39.50 overlay at the start of a session for persistence throughout the Sierra session or to "ask every time").

Even for Sierra users who only want a single Z39.50 Load Profile, adding this feature would also mean that it is no longer necessary to ask Innovative to select a non-default Load Profile for remote search, because it would become "self-serve" in Sierra's GUI.
