  In this paper, we present an approach for analyzing the behavior of editors
in the large current awareness service "NEP: New Economics Papers". We
processed data from more than 38,000 issues derived from 90 different NEP
reports over the past ten years. The aim of our analysis was to gain an inside
to the editor behaviour when creating an issue and to look for factors that
influence the success of a report. In our study we looked at the following
features: average editing time, the average number of papers in an issue and
the editor effort measured on presorted issues as relative search length (RSL).
We found an average issue size of 12.4 documents per issue. The average editing
time is rather low with 14.5 minute. We get to the point that the success of a
report is mainly driven by its topic and the number of subscribers, as well as
proactive action by the editor to promote the report in her community.
