What constitutes a "duplicate"?
Could we have a chat about what constitutes a "duplicate"? I've begun looking into this and it looks like some are actual duplicates (i.e. the words / images / page layout are more or less identical) while others are not exact duplicates (they may have been printed in a different location, may have different prefaces, may use different font etc, even if the body of the text is largely identical). For example, of these three copies of Iron Shroud, https://en.wikisource.org/wiki/Index:Iron_shroud,_or,_Italian_revenge_(2).pdf and https://en.wikisource.org/wiki/Index:Iron_shroud,_or,_Italian_revenge_(2).pdf are identical, while https://en.wikisource.org/wiki/Index:Iron_shroud,_or,_Italian_revenge_(3).pdf is not. Do you agree we would want to delete one of the first two and keep the third? Gweduni (talk) 14:49, 30 April 2020 (UTC)


 * Duplicate to me, means something that is identical in a substantial portion, but I am more than willing to defer to an expert view on this. I don't personally have objections to keeping duplicates, given that duplicates can help reconstruct portions across various printings. Feel free to amend the list, or ask other Wikisource contributors for advice. In terms of any removals, I wouldn't oppose removal if what's being removed is duplicate uploads of the same scan (which I think is rare) in terms of the items I've been dealing with.  Commons I don't think has issue with different printings/editions either.


 * All of the uploaded scans seem to be different printings (if they were duplicate uploads, the NLS id's would be the same as I understand it). I've tried in the list to pair off what I think might be different printings, of nominally the same edition (so that if other contributors wanted to avoid duplication of effort they could). Feel free to amend the list as you feel appropriate. ShakespeareFan00 (talk) 15:56, 30 April 2020 (UTC)


 * That different printings have ended up in the collections would seem perfectly normal to me. ShakespeareFan00 (talk)
