How do I limit a search to a single catalog?

If you are using the NHAIS ILL System as a source of MARC records for your local system you have several options for downloading records. One of those is to search directly in the system and download the records you need. In that case you will want to limit your searches to just the NHU-PAC.
To do this, click on the icon to the left of the search box (it looks like a stack of pancakes) to open up the Resources page, and clear all the check-boxes except "NHU-PAC." Doing that will cause all the searches you do in that session to be limited to just records in the NHU-PAC rather than searching all the connected Ztarget catalogs as well.
