Embargos for electronic journals mean that there are certain limitations to the coverage dates of that particular journal. So if an electronic journal has coverage from 1987-present and has an embargo of 1 year, that means that the journal articles from the most current year of that journal (2013 in this case) will be unavailable until 2014 and that the journal articles released in 2014 will not be available until 2015 and so on. Embargos can be anywhere between 6 months to 2 years. However only a small number of our electronic journals have embargos on them.
