During the presidency of Donald Walker, the History of Economics Society decided that instead of publishing the conference programs and paper abstracts in the HES Bulletin as it used to do, a selection of papers presented at the annual meetings would come out in edited volumes. Thus,  from 1989 to 2000, selected conference papers were published in Perspectives in the History of Economic Thought, a hardcover series published first by Edward Elgar (1989-1995) and then by Routledge (1996-2000).
In 1998, the HES President David Colander proposed to the Executive Committee that the book series to be terminated and that selected conference papers be then published in one dedicated issue of the Journal of the History of Economic Thought (the journal had recently moved from publishing two issues per year to four).
The list of all titles of the Perspectives book series is shown below.
