Moving Wall

Moving Wall: 1 year (What is the moving wall?)

Moving Wall

The "moving wall" represents the time period between the last issue available in JSTOR and the most recently published issue of a journal. Moving walls are generally represented in years. In rare instances, a publisher has elected to have a "zero" moving wall, so their current issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall: Fixed walls: Journals with no new volumes being added to the archive.; Absorbed: Journals that are combined with another title.; Complete: Journals that are no longer published or that have been combined with another title.
