Most papers will undergo one or more revisions. A revised paper
will be entered using the online tool and is sent directly to
the Editor who handled the reviews of the original
version. The tool assigns a number related to the original paper
number by adding a R1 extension (R2 is used for second revision.
If the changes requested and made are minor, you might simply
verify that these changes have indeed been made and then accept
the paper as either a paper or correspondence. This usually
happens when the previous decision was "accept with minor
revisions."
However, many revised papers will need to be sent back to the
original referees for a second round of review, particularly
when the previous decision is reconsider with major changes.
In this case, the reviewers will have access to the original
paper, its decision letter (which includes all reviews of the
original paper), nd the response of the authors to the reviewers.
The online tool does not automatically invite reviewers back
for the revised paper. It does copy the list of original reviewers
and skips the initial "invite reviewer" stage. Thus,
the Editor needs to click the "agreed" button
for the reviewers that will be used again for the revised paper.
Additional reviewers can be added in the usual way.
Generally, if a referee has provided an initial review, it
will not be difficult to obtain a second review of the paper
from him or her. As with the original paper, the tool automatically
sends reminders at 30, 45 and 60 days.
Sometimes an author will accidentally submit a revised paper
as a new paper. If you suspect you have a paper in this situation,
contact the Editor-in-Chief.
