I expect you have heard about the inaccuracies of part lists before.

Since bricklink is now part of Lego, perhaps the bricklink part lists for sets
cold be compared with the Lego lists and corrected as necessary. I expect most
of this could be done with a computer program although it would be nice if one
could get accurate part lists for all those really old sets that one can find
in a friend's great grandfather's attic.

Thank you.

Thank you.

BrickLink has the most accurate LEGO inventories anywhere. They are even more
accurate than what is known by the LEGO Group itself. The inventories are constantly
updated by volunteers as new information is learned.

Cheers,
Randy

No, not here. Yes, there may be inaccuracies, but we correct them whenever they're
found.

We have 15,503 LEGO sets in the BrickLink database, dating back to 1949. Of
those sets, 97.3% have inventories (or parts lists, if you prefer that terminology).

Out of that remaining 2.7% lacking inventories, roughly one fifth are educational
sets and not likely to be found in anyone's attic. If TLG actually does
have a computerized database of inventories prior to 1990ish, then by all means
let's compare.

But our inventories came from what people actually found in LEGO sets. I've
found numerous instances where TLG's data prior to even 2000 is sorely lacking.

I make a distinction between what parts are in a set when purchased (new) and
what parts are actually needed when building the set. It is very rare but once
or twice I have needed a part not shown in an instruction inventory.

Yes, parts lists in set instructions and printed on set boxes are known to sometimes
include errors. I'm more interested in how BrickLink inventories almost
always steer you wrong. Please provide some examples of this and be specific
about how our inventories are inaccurate.

And no, you've not offended me and I doubt you've offended Randy. But
when you post publicly that our site's inventories are frequently wrong,
then we're going to defend the work we do.

I am definitely not offended. If there are errors, I want to know where they
are so we can fix them.

If you are comparing Bricklink inventories to a list of parts needed to build
the set, they will not always match.

Bricklink inventories do not document the parts needed to build the set. They
document the contents of the box.

Might be useful to identify the lists that has parts need to build the set and
the parts that were in the set when issued. Is the extra part section at the
end of some sets the ones that are used but not necessarily in the original set?
For me the important thing is to have all the parts I need to build a set.

That describes the definition of "extra parts" for purposes of the inventory
pages.
Bricklink has a different definition of "extra parts" for purposes of defining
a complete used set.

The extra parts section shows parts included in the box that are not on the "official"
parts list (if there is one). Additionally, any parts that came attached on a
sprue or in standard, bagged "sets" (like small tools and accessories) will
be in the regular section of the inventory even if one or more of the attached
or bagged parts are not needed to build the set.

There is no indication in Bricklink inventories of which parts are needed to
build a set according to the instructions. Sometimes the section of regular items
happens to include just those parts, but it is by coincidence and not by design.

I agree. LEGO could correct their inventory lists based on those at Bricklink.

Did not mean to offend anyone with my post however I beg to differ. I use Brickset
& bricklink inventories to find parts for sets which is second only to the actual
inventory printed in some set instructions. Using only briclink, Brickset list
I will almost always be short some pieces which I check by going through the
instructions and either matching to the on-page diagram or by completely building
the sets.

Regarding sets without an inventory in the instructions, I agree that bricklink
has the best inventories.

Sets with inventory in the instructions, my experience has not matched what you
describe.

If you find an error, please let us know, but I think the statement "Using only
briclink [sic], Brickset list I will almost always be short some pieces" is hyperbole.

By the way, there are many errors in those printed parts lists in the instruction
manuals that have been discovered over time and are fixed in the BrickLink inventories.
So don't assume that those printed parts lists are correct.

Cheers,
Randy

I'm really curious which sets you've run into issues with. I've found
that the Bricklink inventories are far more accurate than the actual LEGO inventories.

The issue with official LEGO inventories is that they don't keep track of
part variants at all. In fact, when a part variant goes out of production and
a new one is added, the official inventories are updated to include the new part,
even if that set never could have contained it in the first place (I first ran
across this with the Cafe Corner set). Bricklink keeps track of specific part
and mold differences, for those that want the most accurate information of what
came in a sealed set box.

Unfortunately, LEGO inventories are good for quantity and color, but for the
actual parts that came in a production set, they aren't always accurate.

I never use the online Lego inventories, in fact I wouldn't know where to
find them. What I do is print or photocopy the pages in the set instructions
and use those as my primary list for parts that should be in a set. I augment
that with Brickset and bricklink lists.
The 3D function on briclink is especially helpful.

For most sets, Brickset = online LEGO inventories
