I created a collection of 11 items called Parenting. The Resulting Collection table shows all 11 items. The first column is called "Rank."

What is the meaning of Rank in the context of Collections?

Is it possible to change the rank of each item? If yes, how?

Thanks,

Aaron

No, you can not change rank. It has the same meaning in collections as it does in the library. The calculation of rank varies by context but it is basically an automated estimate of relevance.

It's carried over from the Library, where it describes how well a result matches the query (where 1 = best).

In Collections, it doesn't have any meaning; the "rank" of a resource within a collection doesn't affect any features in the software.

Thanks for your quick feedback! Based on how it behaved, I wondered if this was the case.

Has your team considered changing the name of this column to something like ID or Item #? I believe that would clear up the confusion I had and prevent users from trying to do something that they really can't.

As you know, losing time because something doesn't make sense frustrates a user. :)

I think that many users would get confused when they discovered that ID or Item # was not a stable value.

Interesting... I was left with the impression that rank is for search results. When books are in a collection, it's not a search result. And that's the source of confusion for me. What does rank truly mean in the context of a collection? I understand what it means in the context of search.

Having said that, I could understand what rank means in the context of collection if by that Logos is attempting to assign the relevance of a book to that collection. I can relate to that understanding of rank, if rank is tied to what is entered in "Start with resources matching:" on the Collections dialog. But if that's the case, when I manually insert books into a collection, rank doesn't make sense unless I get the opportunity to edit it.

And if that is what rank means, shouldn't books in a collection be allowed duplicate values for rank? Perhaps I'm being overly pedantic, but I'm trying to consistently apply the English meaning of "rank" to the context of Collections.

For example, if I place multiple books in a collection that I call "Parenting," it would be nice for me to rank the relevance of those books to the topic at hand. Some books might not primarily be about parenting but might cover things pertinent to parenting. I would rank those books lower. And I would like to assign equal values of rank for certain books.

IIRC this information applies: Tf-idf ranking routine (sequence by rank) | Wikipedia. To me, "rank" describes the field more than id or item # both of which imply to me a fixed, arbitrary number not the result of an algorithm.
