What Identifyer is "wd"?

[Rellwood]

I have a few identifiers and a column for them, but I have no idea what they are for, and where they came from. I only have 27 books out of 5000 entries with it, but I would like to know what it is. Starts with a "Q" and has numbers

Here is a list from Patricia Briggs "Siverborn" (oh and ignore the imojis)

Have considered that you have too many IDs? Especially where multiple IDs with the same value exist such as your amazon, asin & mobi-asin triplet or your ISBN10/13 quintet.

That aside, I would suspect that your Q27453434 id comes from Wikidata. A quick check might be to see if you have the WikiData metadata plugin installed and if you own Hunting Ground by Patricia Briggs, it shows wd:Q27614675 as an ID.

BTW, it took about 1 minute to find that information.

Click on it in book details. If there's a link associated with it (either custom or via plugin) it'll open the browser.

I have all the id's to make sure that the information is correct in Goodreads, Library Thing and My own library. I also use the identifiers to import the csv files of their libraries to make sure that they are synced.

I don't know why I didn't try and click on the link in details.

If I am having trouble figuring out why a specific book in Library Thing isn't matching up with what I have in my library then I can see the identifiers used to get it right. Also, in order to IMPORT into these and other online libraries you need to have the ISBNs

I even have one for the different Amazon id's so I can import the reading session and whispersync and audible data from their website.

I'm a data hoarder, most of this stuff is just so I can import the catalogs. Plus it's helpful in identifying books across libraries if they are all the same.
