Elsevier embargo periods, 2013-2016

***Update***: as of June 2016 the 2016 embargo list has been revised. The data below has been updated to reflect the new embargos.----This dataset contains all journal embargo periods published by Elsevier in 2013, 2014, 2015, and 2016, for both UK and non-UK authors. It also contains a set of notes on the overall statistics and annual changes between lists. In summary, 88.5% of Elsevier journals (in 2016) offer a twelve-month or less embargo period for UK authors, and 62% for non-UK authors; this proportion has increased since 2013, as has the number of journals covered. The majority of journals have a stated embargo period, though around 50 titles do not as yet have one. A number of substantial anomalies developed between the lists in 2013 and 2014, with journals being removed or having their embargo periods extended. However, as of 2016, these have generally been corrected.
