Choose Databases Selection Limit

In an effort to conserve resources on database servers, BookWhere by default limits the number of databases which can be selected to 250 for a given search. Previous versions of BookWhere did not impose a limit, however, due to communications timeouts many searches were being carried out needlessly since the client machine running BookWhere could usually not keep up with returning results. Even the limit of 250 databases is probably too high and we suggest that users create one or more database groups with no more than 30-50 databases. If a database group is carefully created, adding libraries that carry similar materials to your own, the chance of a match when searching this group will be just as good as when trying to seach hundreds of libraries at one time.

If you would like to increase this default limit, the value can be changed from the menu:

Options-->Setting-->Communications

Change the value of 'Maximum number of databases that can be selected for a given search:'
