Book metadata sometimes not updating

bob.f · 12-09-2018, 09:03 AM

I have noticed some odd behaviour with the Download metadata functionality accessed via the Ctrl-D shortcut.

Typically, after I import a bunch of books into Calibre I will update the metadata to fix e.g. missing covers or tags. Let's say I do this for a dozen books, five of which might have missing metadata.

The job will run in the background and when it has finished I will accept the changes. Of the five books I wanted to update maybe three actually did. This leaves two books still with missing metadata.

Initially I thought that the metadata search function was simply unable to find covers and tags for the remaining books. But what I discovered was that if I ran the metadata update again on the remaining books that still did not have metadata, as often as not the covers and tags were found.

So, my question is: why does Download metadata need to be run more than once on the same selection of books in order for them all to be updated?

Do you use any plugin for this task?
I use the goodreads plugin and I never had problems.

Server congestion, times out (do not tamper with the delay tweak, that is there to reduce the chance of overloading and possibly getting Calibre blacklisted) (affects ALL of us)
