Many years ago, Technical Services had a sizable backlog of both Western language and non-Roman language material. Anyone looking for a title in processing could send a message to the list and someone would mount a search for the title and locate it in the processing stream. The Non-Roman backlog is a bit larger but still significantly smaller than in the past.
Material now moves through processing in a relatively short period of time.
As a result, the librush list is seldom used. When a title is needed from the processing flow, most people simply contact the person they work with most in processing and ask for assistance. For example, for monograph titles, the bibliographer searcher assigned to your subject area would be a logical choice. We hope that this is just a formal recognition of the way the process has now evolved. Please let me know if you have any questions or concerns.
