Firstsearch is a catalog of materials from libraries across the globe. Firstsearch includes books, websites, films maps, musical scores, sound recordings, videotapes, and more.  Use Firstsearch to search for books and other materials available from other libraries.  Marengo-Union cardholders in good standing can request identified items from Firstsearch by calling the library (815.568.8236) when the library is open.  Due to changes in this service, patrons can no longer request interlibrary loan items online.
