An important task for bulletins is to find ways to reward reviewers. This may be by mentioning their names in the bulletin and/or paying them and/or sending them a present. Many ISDB bulletins send them reference books or cheques to buy books, or offer a free subscription to the bulletin or perhaps a special issue or guide produced by the bulletin. It is useful to send feedback to reviewers on their comments. Some bulletins send personal letters, others send circular letters summarising the comments of reviewers and how they were incorporated into the article. Occasionally reviewers may ask for certificates acknowledging their role.
Some bulletins have systems in place to evaluate the quality of reviewers’ work. Even without such a system, it is a good idea to check regularly if reviewers are not too overbooked, or less critical, or if some change in their professional life has affected their ability to review.
