It can be very challenging to locate information about individual ISU Extension publications via the library website. Quick Search will list the name of the series, but it will not list individual publications within each series. The Parks Library Reference Collection has a List of Current Series, Serial Publications (Series Publications of Agricultural Experiment Station and Cooperative Extension Service), published as of March 2004. It lists each publication from 1888-2004 (by title and publication number - and in some cases it will show an author name).

If you know about an ISU Extension publication but cannot locate it in Quick Search, the Extension series notebook, or the cheat sheet linked below, check with Special Collections staff on the 4th Floor.
