Here is the Find Articles screen.  This is where we moved the remote repository connections, all of which are Z39.50.  Users can search one to eight databases at a time, down to the article level.  We limited the number to eight for two main reasons:
	1.To optimize performance.   In this federated searching environment, the response time for the overall search equals the response time for the slowest repository selected.  We wanted to limit the number of databases selected per search to a reasonable number.
	2.To address licensing issues.  Some databases allow for a small number of simultaneous users and/or stipulate a per-search pricing structure.  By limiting to eight databases, we hoped to lessen the chance of users being locked out due to the “too many simultaneous users” scenario, and we hoped to avoid exceeding our per-search limit where it applied.  Unfortunately, the only text users see when they are refused a connection is a rather generic “search failure” message and currently we are not able to tailor the text of that message to be more specific.  Also, we did later find that some resources we included on this page which were on a “per search” pricing structure ended up getting unprecedented numbers of connections, and so some resources either had to be removed from the Find Articles page or the license agreements had to be reconsidered.
