WHAT IS A MOVING WALL?

Some publishers set a "moving wall" to limit access to recent issues of a journal. The moving wall is the time period between the latest issue available as full text and the most recently published issue of a journal, expressed in the number of years. The current year is not counted when calculating the moving wall. For example, if the current year is 2017, a journal with a 5-year moving wall will be available through the year 2011. Issues within the moving wall period generally have tables of content and abstracts available.
