How to bulk select and deleted duplicates?

So, have a lot of duplicates, not a clue why.
At My books there's no option to search for duplicates.
Oddly at my profile>charts & graphs>odd and end there is the list of my duplicates.
But it doesn't allow to select / delete them.
Can't go through hundreds o entries to delete each one manually, it doesn't makes sense if the systems do can find and list my duplicates.

So, how does it works?

thanks

When you are looking at the "Your Books" tab, look at the secondary header.
You should see a lightning bolt icon

Click on the lightning bolt to activate Power Edit mode.
This will allow for selections and mass deletions.

Be sure to turn it off when done, otherwise it could cause unintended problems later.

There have been requests to show duplicates in the catalog for easy deleting, but unfortunately it doesn't exist yet.

That helps mass delete once the books are selected, but doesn't give you a list to delete.

You also have plenty of work duplicates that aren't just simple duplicates where it doesn't matter which you delete. In some cases there are both English and Portuguese copies. Work duplicate lists also often contain cases where the autocombiner has combined various volumes into one work, and that needs to be checked for.

The work duplicate list lets you check whether the books are really duplicates. Even if most of it is a bad import, LT isn't set up to make those decisions. Many members deliberately have multiple copies. Duplicates may not even be in that list if they didn't end up in the same work.

>2 gilroy: I know, but still have to browse may entire library to select every single duplicate that i need to delete.
Would be really useful if that option was available at profile>charts & graphs>odd and end. At least the duplicates are already listed there

>5 BlackfoxDJ: You only asked how to do it. So that's how I answered.

I know this isn't very helpful right now, but it might help you avoid this problem in the future: every time you add a duplicate in 'Add books,' it will tell you that your entry is a duplicate. Most of the time, this is a small italic notice under the entry in green. In English this notice reads, 'There is another version of this work in Your books.' If the ISBN is the same as another book, you will get a notice in red which will say something similar.

If you pay attention to when these pop up, it will be easier to stay on top of duplicates. If you click on a book which has duplicates, under 'Your book information' it will say 'Your other editions' and list the title you have given for that entry (with a link to that version of the work), the author for that entry, and the publishing information listed for that entry. You can use the information there to compare and determine what the next action needs to be for your specific library.

If you realize you accidentally put one book that you own into your library multiple times, this is when it is easiest to delete the book.

If you do actually have multiple copies (and intend on keeping both in your library), you don't need to do anything else. I know this can get irritating if you have copies of one book in multiple languages, because I wouldn't consider that a duplicate of the same book, but that's the way that LT is set up.

If the two books really are different works, like different volumes of a similar set, two books which share a title or an ISBN (it does, occasionally, happen) and were mistakenly combined or assumed by the LT system to be the same, or any other such issue, you now know exactly which work to separate. If you have trouble with this part, or don't know what to do, there is a Combiners! group here in LT that is happy to help.

I know that may not help you right now, but hopefully it will prevent the same problem from happening again in the future.

I suspect that you did a universal import twice for many of those. As for solution, I doubt that anything is quicker than just opening obvious duplicates (meaning you see it's not 2 different editions of the same work, but clearly an unwanted duplicate record) from that stats page that lists all duplicates. Just open them in new tabs and delete. It shouldn't take more than 15 minutes.
