To add to the publication date idea, I use this function as well. There is a certain reference book on vacuum tubes I collect that was issued in different versions. Having the publication date and/or version of reference manuals that have the same name makes it easier to find the version I am looking for.
Other books I collect have similar issues, so the use is there at least for me. 8c)
