ABCD-Spectrum Cataloging Manual
Introduction
The present standardization of the ABCD-Spectrum database is based on two fundamental pillars: the international standard Spectrum - the UK Museum Collections Management Standard (Collections Trust), widely recognized and adopted by museum institutions in several countries, and the CHCM Museum Cataloging Manual, an internal document that consolidates the technical practice developed over the years at the Mackenzie Historical and Cultural Center (CHCM).
Spectrum 5.1, published in September 2022 by the Collections Trust (United Kingdom), represents a continuous effort to review and improve documentary processes through the rethinking cataloguing initiative, which seeks to make cataloging more accessible, clear, and effective. Its principles directly guide the organization and development of the museum collection management practices at CHCM, serving as a methodological basis.
The ABCD System (Library and Documentation Centers Automation), in turn, is a free, robust, and customizable solution for collection management. Originally aimed at libraries and documentation centers, the system has been adapted to meet the specificities of the museum collections of various institutions, bodies, or individuals, allowing the integration of Spectrum guidelines into the software's functional structure.
The construction of this database model, therefore, results from the articulation between the parameters established in Spectrum and the practical experience consolidated in the CHCM Museum Cataloging Manual. This standardization aims to guide teams in the standardized use of the database, ensuring the consistency of records, information traceability, and the preservation of memory.
Who is it for?
Spectrum is for museums of any size and any type of collection, and can also be useful for similar institutions with museum-like collections. To keep things simple, we use "museum" to cover all collection-based organizations, and "you" to mean everyone involved in managing the collections under their care: from governing bodies that set policies and budgets to all levels of staff and volunteers, both front-of-house and behind the scenes.
What is in a Spectrum procedure?
Each procedure has:
- A definition that attempts to summarize the procedure in a single sentence.
- A fuller note on the scope of the procedure, explaining when to use it (and sometimes when to use a different procedure).
- The Spectrum standard. This is what you should aim to achieve, no matter how you do it. The standard has two parts:
- Some policy questions you will need to consider.
- The minimum requirements you must meet in your own museum's written procedure. An example or two suggests why each is important.
- A suggested procedure (and it is only a suggestion) given in two formats:
- A workflow diagram summarizing the suggested way of doing things.
- A text version, which includes the information requirements for the procedure (see below). Where necessary, the text versions of the suggested procedures also include guidance notes.
The important thing to emphasize immediately is that there is no single way to put any of these procedures into practice. Whether your museum uses paper-based systems, a computerized collections management system, or — most likely — a mix of the two, you can adapt the suggested procedures to meet your needs. As long as your museum's way of doing things meets the minimum requirements of the Spectrum standard, your documentation should be fundamentally sound.

0XX - Object Identification
002 - Registry Number (Accession Number)
The Registry Number is unique and sequential information aimed at classifying and identifying an item in a collection. It is understood as a mandatory description element and constitutes one of the main access points to the item.
It is suggested to use the following descriptors:
- Custodial Entity (mandatory): Information designed to identify the institution that stores and preserves the museum item. By standard, this descriptor is accompanied by the code of the country where it is headquartered. This allows museums to exchange information about their collections in web ecosystems and identify their geographical location. For the country code, the use of ISO 3166 Codes for the representation of names of countries is recommended (e.g., US for the United States).
- Custodial entity subunit (optional): If the institution has more than one physical address, it is necessary to register a specific code for each subunit that carries out storage and preservation. It is suggested to build a numerical representation expressing this condition.
- Museum Collection (mandatory): Information designed to identify the collection grouping.
It is composed of levels of information:
- Custodial Entity is the entity responsible for gathering the items. As a rule, the acronym of the country where the entity is allocated is used first. (e.g.,
US_MUS) - Collection is the indication of who gathered the items. (e.g.,
ART) - Classification is a grouping of typologies.
- Number is the sequential identifier with seven digits and the addition of its typology.
Example: US_MUS_ART_FURN_0000001_Furniture
The following broad denominations are suggested for classification:
- Archaeological (AT) – E.g.: artifacts found in excavations.
- Visual Arts (AV) – E.g.: drawings, engravings, sculptures, and paintings with various themes.
- Equipment (EQ) – E.g.: voltmeter, cameras, theodolites, and precision balances.
- Geology (GEO) – E.g.: minerals and rocks.
- Heraldry (HE) – E.g.: coats of arms.
- Clothing/Garments (VE) – E.g.: gowns, sashes, hats, shirts, and uniforms.
- Furniture (MB) – E.g.: cabinets and chairs.
- Numismatics (NM) – E.g.: coins and medals.
- Object (OB) – E.g.: dolls, test tubes, and generic objects used in classes or created for a commemorative date.
- Awards (PR) – E.g.: trophies, diplomas, plaques, as long as they are not merely commemorative.
- Vexillology (VX) – E.g.: flags and pennants.
In the case of sets, a new sequential number will be added to identify the items that compose it:
- *Ex.: A precision balance with 5 weights.
- The set:
US_MUS_ART_EQ_0000001_Tool - The balance:
US_MUS_ART_EQ_0000001_Tool_1 - Weight 1:
US_MUS_ART_EQ_0000001_Tool_2 - Weight 2:
US_MUS_ART_EQ_0000001_Tool_3 - Weight 3:
US_MUS_ART_EQ_0000001_Tool_4 - Weight 4:
US_MUS_ART_EQ_0000001_Tool_5 - Weight 5:
US_MUS_ART_EQ_0000001_Tool_6 - Packaging/Box:
US_MUS_ART_EQ_0000001_Tool_7(only if original to the piece; if not, just describe it in the "physical description" field)
- The set:
*Note: Constantly updated, as it is linked to the acquired collection.
020 - Classification (Object Category)
Used to insert the taxonomic classification.
050 - Title / Denomination
The title of the object must be transcribed in this field, according to the information collected from it. When it is not possible to find the denomination, the field can be filled with a title assigned by the person responsible for the registration, in brackets, in order to facilitate its identification.
The denomination of objects and furniture follows synthetic criteria and makes no value judgments. Sets follow the same denomination criteria as individual objects, and when composed of only two identical pieces they will receive the denomination "pair" and larger groupings "set". Pennants, Trophies, Medals, and Coins have specific denominations referring to the producing body and the event, respectively.
Therefore, for this field, there are the following types of insertion to consider:
OBJECTS IN GENERAL: Transcribe the main title, especially considering visual arts, whose author may have assigned a title. In other objects, this information may be contained in the packaging boxes.
- Ex 1: Boats in the Marina
- Ex 2: Microfilming lenses
Assign a title: if the object does not have a specific denomination, a generic but universally known denomination can be assigned. Place this type of title in brackets. For visual arts, pennants, trophies, and medals, make the mention "Untitled" and then, separated by a semicolon, add the assigned title, in brackets.
- Ex 1: Large scale [Precision Balance]
- Ex 2: Chemistry glass [Pipette]
- Ex 3: Untitled; [Shipyard]
- Ex 4: [Pair of Armchairs]
- Ex 5: [Table and Chairs Set]
PENNANTS / SASHES: Transcribe the main title, considering only the producing body. If this information does not exist, or if it is an event with shared production, use the name of the event. ALWAYS use the word "Pennant" or "Sash" in the denomination and AVOID using abbreviations, even when they are on the object. Research the information for the meaning of the abbreviated text.
- Ex 1: Student Union 2020 [Student Union Banner]
- Ex 2: 3rd Annual Tournament
- Ex 3: Class of 2015 Law School, [Law School Banner]
- Ex 4: The Museum [Museum Banner]
TROPHIES / MEDALS / COINS: Transcribe the main title, considering only the competition/event. If this information does not exist, due to loss of information on the identification plate, assign an "Untitled" denomination. ALWAYS use the word "Trophy", "Medal", or "Coin" in the denomination and AVOID using abbreviations.
- Ex 1: State Cup Trophy; [State Football Championship Trophy]
- Ex 2: Regional Tournament Trophy
- Ex 3: Science Fair Medal
- Ex 4: 50th Anniversary Commemorative Coin
