In https://www.researchgate.net/profile/John-Gillespie-Jr/publications you may sort your papers by time (oldest or newest first) or by title. There are about 30 publications for which the date and bibliographic details are missing. These appear first in the list when you sort by oldest. You may go through all 824 publications and edit the data, or you may search for titles of selected publications. Unfortunately, it is not possible to search for the year of publication. ResearchGate's search form is very simple, there is no advanced search. And rather often, the list of publications is not complete, but you may complete it "by hand". Some of the missing publications may be in ResearchGate, but not yet attached to your profile. You may search for these with https://www.researchgate.net/search.Search.html?query=&type=publication.
