Take note: In calculating the relocating wall, the present year is not measured. In uncommon instances, a publisher has elected to have got a 'zero' relocating wall structure, so their current issues are obtainable in JSTOR quickly after distribution. Moving walls are generally manifested in decades. The 'shifting wall structure' symbolizes the period time period between the last issue obtainable in JSTOR and the almost all recently released concern of a journal.
