If you will exclude some self-promotion from the Editor, last month my book A History of Enterprise Search 1938-2022 was published under the PressBooks imprint of the University of Sheffield.
If you have cause to doubt that there were any enterprise search initiatives in 1938 then you should certainly read this book. Enterprise search has been around for a very long time.
