This is what the rules states:

Quote:
A simple list of Episodes may also be added to the standard overview. Do not add episode synopses to the overview field, but these can be added to the local non-contributed “Notes” field.

Sounds good, but I have come across so many profiles that enter them differently.

Some is just a list of episodes, some are just a list, but with 1. in front of the episodes.
Some use bolding, italics or just standard text for the header of "Episodes".

For example I have come across these. Some of the examples use bolding or italics for the Episodes header.

No header at all, just the episodes

1. Title
2. Title

Episodes:

1. Title
********

Episodes:
1. Title
"*******

EPISODES:
1. Title

EPISODES:

(Episode List)

I know that it's a little thing, but I think it would be good to have a standard way of entering these, because even in the same series episodes are entered differently sometimes from one season to another.

Personally I like:
Episodes:

1. Title

I dont believe there is a standard, but I know from experience that some have strong feelings about it. I have had no votes on contributions that added a list of episodes with the unformatted header:

Episodes:

on the ground that the rules require a simple list of episodes.

No header might be fine if there is nothing else in the overview. A header becomes useful, however, to separate the list from the text taken from the back cover.

EDIT: Also, what to do when dealing with several seasons packaged together, like in Naked City: The Complete Series (014381863826) or Sports Night: The Complete Series (826663109290)? Should not there be a header of some kind to separate the seasons in the list?

I definitly prefer headers per season in this case:

Quote:
Season 1:

1. Title
2. Title
...

Season 2

1. Title
2. Title
...

And I prefer starting the counting for each season with 1!

But both is not covered by the rules anyways, neither forced nor forbidden...
