You may ask, "Why did our ISSN center feel compelled to change the number that had originally been assigned by them to JGR?" I certainly did. The answer was tied to the fact that AGU changed the cover design when the trim size of AGU journals was increased from roughly 6 x 10 to today's size in order to cut costs. With the additional real estate we decided to add what we thought - and still think - was a design element: the big block letters J G R. We did not change the title of the journal. (We had been sensitized by our colleagues in the library community about the problems created by title changes.) The LoC told us otherwise. Because the design element contains letters and was the largest thing on the cover, they, not AGU, changed the name of the Journal of Geophysical Research to JGR Journal of Geophysical Research and a change in the 'key title' triggered a change in the ISSN.Not yet available on the Web site.
