Publisher permissions and embargoes

Over 60% of journals permit authors to self-archive their articles, some without any embargo period at all ,before they can make them Open Access. Any institution implementing an Open Access policy should advise authors on where to find out what the permissions conditions of their favourite journals are.

The information is collected in a database compiled by the SHERPA project at Nottingham University and by the EPrints service at Southampton University. These show the permissions by publisher and by journal: authors can refer to these to find out what embargo period they need to set when they self-archive an article if their institutional Open Access policy accommodates a publisher embargo (see the optimal Open Access policy and the types of Open Access policy that an institution can implement).

Currently, the permissions by journal and by publisher are as shown in the charts below:
