[seqfan] Re: Position of new material

This recent correspondence with Neil may be of some interest:


I have a question regarding the submission of a Comment that is a
generalization of a previously submitted Comment by someone else; namely,
what is the proper way to indicate that the new Comment is a generalization
of the old Comment?  If the new Comment immediately follows the old one,
then there’s no problem.  But suppose there are quite a few unrelated
Comments following the old one.  

I can think of 3 ways to handle the situation:

1. Submit the new Comment out of chronological order immediately following
the old one;

2. Submit the new Comment at the end of the list with a reference along the
lines of “See related Comment from Feb 13 2007.”;

3. Just submit the Comment starting with “In general, ...” and let the
reader figure it out.

Perhaps there’s another.  Thanks for your perspective.


Charlie, sorry for not replying sooner (my VPN gadget expired).

I think no. 1 is by far the best.
Put the new comment right after the old one.

 Best regards

Charlie Marion

Again, I'm not proposing mass editing of existing sequences.

But I recently added comments to a couple of sequences in what I 
considered appropriate positions, and had an editor say "no, they 
belong at the end" and move them there.

What I'm suggesting is that these rules are desirable, and we should 
try to move towards them rather than away from them.

I largely follow rules similar to Franklin's when adding new material.
 In short: if there's a good reason for it to be in a particular
place, put it there, otherwise put it at the end.  I don't rearrange
existing material unless there's a special reason for it.

Longer entries could use some work, though I haven't attempted to put
any kind of order to them in the past.  There are I have tried to
limit material in those entries.  For example, I move
peripherally-related information to other sequences when possible.
For example, if a comment was proposed for A000040 that said:

For all members p of this sequence, p+1 has the property ...

I would tend to move this to A008864 which has less material and is
more closely related.
