HELP - Set Types

Rebrickable's set catalog contains several different types of sets:

• Normal Sets: official LEGO sets. These sets contain one or more models, or a collection of many different parts (Bulk Bricks).
• Accessory Sets: known as Supplemental Sets (1950 to 1970) or Service Packs (1970 to 2001 / 2002 to 2012 Dacta), these sets do not contain models, but small collections of a few special parts.
• B-Models: many LEGO sets contain instructions for one or more alternate models. These official alternates are called B-models. Unofficial alternate build, not created by LEGO, are stored as MOCs.
  • LEGO Idea reBuilds (LIBs): Also known as C-Models, these are a type of B-Model. These are rebuilds of models included in LEGO Idea Books, or alternate models shown at the back of box, for which LEGO never released official build instructions.
• Sub-Sets: sometimes a LEGO set contains a multitude of small sub-sets. An example would be an Advent Calender. See below for a detailed description.
• Super-Sets: official LEGO sets that contain two or more Normal Sets. Also known as Value Packs or Kits.

But we also include other LEGO related items:

• Books: official LEGO publications or Books from other publishers under license from LEGO.
• Games: Dimensions, PC- and board-games.
• Key Chains
• Posters
• Other Gear

We do NOT include:

• LEGO-like sets from other manufacturers
• Magazines and Books from publishers that are unofficial.
• Catalogs and boxes

What qualifies to be a sub-set?

When a set has multiple components to it we can create a sub-set for each individual model. For example set 60233-1 - Donut Shop Opening. The set contains two buildings and five vehicles. So each model may qualify to get a sub-set.

However there are other considerations. In set 60233-1 one of the vehicles is a police motorcycle, due to the size and nature of the type of parts used this is more of an assembly of parts rather than a sub-set and does not qualify. A sub-set should also avoid dividing up a model. If a building can separate like with a modular building set each separate section does not qualify as a sub-set. Individually a section does not create a model that is intended to represent something by itself. A sub-set model must be whole and complete.

Another thing that would exempt a model from getting a sub-set entry is if the majority of the set is used to build the main model. For example set 41693-1 - Surfer Beachfront. The set has the house and a car. The house is the main focus of the set and does not qualify to be a sub-set but the car does qualify.

Lastly, you need to consider how useful it would be to have a model as a sub-set. It serves no useful purpose having endless sub-sets of things that no-one would want to use. For example set 75332-1 - AT-ST. The AT-ST and Speeder are good candidates for a sub-set as they have broad interest. The small tree section however has very limited appeal and uses a low number of parts so does not qualify to be a sub-set.

When submitting a sub-set go down this list. If the answer is ever yes then you shouldn't be submitting it.

• Is it an incomplete model?
• Does it use a limited number of specialized parts?
• Is it the main model in the set?
• Is the model of low appeal and usefulness to other LEGO builders?

The Set Numbering depends on the Set Type. For Normal and Supplemental sets we use the LEGO set number followed by "-1" (in the past, LEGO used the same set number for different sets, forcing fans to invent a suffix). B-models have the full set number followed by "-b1", "-b2", etc.; for Sub-Sets we use "-s1", for Sub-Sets of B-Models "-b1-s1". Super-Sets sometimes have an official LEGO set number; if not we use the set number of one of the included sets, preceded with a "K" (for kit) or a "C" (for collection). Models seen in books, leaflets, magazines, or instruction manuals that do not have step-by-step instructions for them are called LEGO Idea reBuilds (LIBs) we use the prefix "-c1". Here's an example based upon an imaginairy LEGO set 8258:

• Normal Set: 8258-1
• Supplemental Set: 8258-1
• B-Model (where LEGO released instuctions): 8258-1-b1 / 8258-1-b2, etc.
  • LEGO Idea reBuild (LIB)/C-Model: 8258-1-c1, 8258-1-c2, etc.
• Sub-Set: 8258-1-s1 / 8258-1-s2. etc.
  • Sub-Set of B-Model: 8258-1-b1-s1, 8258-1-b1-s2, etc.
• Super-Set: 8258-1, K8258-1 or C8258-1

Foil Packs used to have a letters prefix. For example, 891612-1 has NIN for Ninjago added to make the set number NIN891612-1. We are currently removing these prefixes. New foil packs can be submitted using the original LEGO set number (with a -1 postfix).

Advent Calander Sub-Sets have a standard numbering and naming system, making them all uniform:
- Set number xxxxx-1-sy, xxxxx being the number of the main set, and y being the day. You don't need to add a 0 to days 1-9.
- Set name: YEAR - Day y: name of the build

Random Foil Packs usually contain a basic brick collection and a random minifig/duplofig. These sets all have the same set number, followed by -1, -2, -3, -4, etc.

For Books and Gear our preference for set number is as follows:

• Official online LEGO number
• Product number/code
• Official packaging LEGO number
• Packaging Identification number
• ISBN number
• Online number from other source (like a sales site like Amazon)
• Made up number due to lack of any available number info

The product code for gear depends on the type of gear

• Keychains/key lights usually have LGLKE
• head lamps LGLHE
• torch/flashlight/desk lamp LGLTO/LGLTOB
• nightlights LGLNI
• book lights LGLCL
• new stationery produced by IQHK and Santoki usually has a 5 digit code (including magnets)
• Bags and Stationery produced by GPL bags have an ID made of a product code and a design code put together. E.g 101032403 with 10103 meaning wallet, and 2403 meaning Ninjago family.
• Gear sets released on lego.com usually have the format 854XXX (most commonly key chains, magnets and role-play toys) or 500XXXX

If you want to submit a set, and you are unsure about what set number to use, please post a question in our forum.
