Non-book (manual ?) entries creating two separate works

One that is linked from the user's profile as newly added yet shows 0 holders, and another that's got the holder but isn't combined with the first (though combining them is easy as they seem to always appear in suggestions for each other), that second one may also have a blank title until one recalculates or things correct themselves on their own. One of the two also won't carry the media tag that was selected on the manual add page.

Examples of entries that exhibited this behavior (first isn't mine but a DVD added by someone who asked about it in Combiners, second is a videogame I added as "software") :

http://www.librarything.com/work/16531523/editions
Video Recording — Hairy Maclary DVD/Frizzel, Ivan/Manual Entry (1 copy separate)
Hairy Maclary DVD/Frizzel, Ivan/Manual Entry (no current copies separate)

http://www.librarything.com/work/16498250/editions
Other — King's Quest 5 : Absence makes the heart go yonder/Sierra On-Line/Manual Entry (1 copy separate)
King's Quest 5 : Absence makes the heart go yonder/Sierra On-Line/Manual Entry (no current copies separate)

I don't think the non-book issue is pertinent here; I had some weird behavior from a manual addition this morning, too. Books added manually before and after had no problems, so I'm assuming it was a transient hiccup that will sort itself out.

When I added it it took a very, very long time to actually be added and then showed up three times in my catalog and on the "Add Books" page. I deleted the duplicates, and now it's showing with no members.

>2 lorax: I'm seeing the edition you linked to with 1 member now (you).

>1 Jarandel: If you still have duplicate entries, you should be able to delete them. I suspect @lorax was right in that it was a hiccup in the system. I just tested adding books manually to my account with no duplicates. Let me know if you're still seeing issues!

Yes, it resolved itself overnight, as I suspected it would.

It's not dupes in my library, it's an extraneous non-combined LT work created in the process, with the media tag on it while the copy that appeared in my catalog doesn't have it. I left them uncombined this time so they can be seen better. Wouldn't classify it as a hiccup since it's happened on all my software entries since media types were introduced or maybe just a bit afterward.

Has one holder (me), but it didn't get the "Other" media tag in editions listing, and is temporarily displayed as "No Title" at the work level, that can be easily recalculated or will go away on its own since it *does* have a title but why is it displayed as having none at first when I entered one ?

0 holders, has the media tag

Interesting. I signed in as you, and both works had 0 holders, yet on http://www.librarything.com/work/16555609, your book information was displayed (indicating you owned *this* work and not the other).

I recalculated the title and cover for 16555610, then combined it with 16555609 and recalculated users (which corrected the members owning the work to 1), but yes, something's going on with manual additions and potentially the media field. I'll try to test this out further this week to pinpoint any details.

Okay, here's what I've found after further investigation:

1. No Media and Book Media designations do not add duplicate editions during manual entry.

2. Sound Recording, Video Recording, Other, Multimedia, and Unknown Media designations do create duplicate editions during manual entry:

- both editions show the appropriate Media field
- primary edition is in my library, and shows as having 1 member owning the book
- duplicate edition shows up under primary edition’s “Editions” page, and has 0 members.
- the Editions page for duplicate edition doesn’t show any Potential work combinations (probably because it doesn't have any members owning the edition)
- duplicate edition changes author from “Test, Test” to “test, test"

Duplicate Edition Sample Screenshot:

Zero-copy editions are created whenever you change the title, author, or isbn of your book, and you were the only person to have that specific title/author/isbn combo in the system. So, I conjecture that during the process of adding one of those media types that you list, it creates the catalog record and then changes the casing on the author for some reason which is what creates the zero-copy "duplicate".

I'm not sure that's actually a bug though. Extra zero-copy editions floating around shouldn't really affect anything except aid auto-combining.

>8 jjwilson61: That's an old behavior.

Creation of a 0-copy when listing a new item with no user action that should result in it is new to manually adding Software and other types of entries as listed in >7 kristilabrie:

Yes, but it's not clear to me that the creation of a zero-copy edition by itself is a bug. The creation or not of zero-copy editions is part of the internal workings of LT which is mostly invisible to users. If there's a bug you need to tell us how this zero-copy edition causes problems to an LT user.

>10 jjwilson61: Because that's the one that's linked from my catalog and profile page, when I should be a holder of it ? Because it doesn't have the media tag it should have when I listed it ? Because part of the information has for some reason wandered off to another uncombined work spontaneously generated during the process, when no such extraneous work appears for other media types, and when I've not altered anything myself in a way that would explain the appearance of a 0-copy with the "old" data ?

It's not a big issue, and I can combine stuff myself and go on with my business if the final answer is that it's not going to be looked at, but it's messy and a departure from normal operation for other media types.

A zero-copy edition that is linked to from your catalog should indeed qualify as a bug.
