Using pressing plant information to find wrong information in releases in Discogs is something that I explored in an earlier post. I only looked at a single pressing plant and that already uncovered 76 releases that were obviously incorrect.
I added a few more checks for pressing plants to my scripts and processed the latest Dicogs data dump that I could find. Immediately hundreds of more errors popped up, and I didn't even add that many companies to my checks. With the new checks I could find 610 that are wrong, but I am sure that as soon as I start adding more checks many more errors will pop up.
What often seems to be the case that people have combined the original release with reissues, making the entries completely useless for a correct classification.
One thing that I noticed when looking at the pages for the manufacturing plants is that there are quite a few where it is mentioned when a certain plant started making either CDs or glass masters for CDs, but usually without (much) proof of the date. For example, the page for Dureco originally said that the plant started making CDs in 1988, based on a link to a weblog from former Dureco employees. Some research (newspapers, Dutch national TV news) showed that this plant actually started making CDs in 1987, not 1988.
Now it sometimes seems closer to "oral history" and people simply assuming that the information on the label pages is correct. Having more external references about when plants were operational would make checks for release years a lot more useful.
