Complete Bibliometric Profile of Burauen Community College Library: 2026 Book Collection Census by Dewey Decimal Classification (DDC)

Technical Note: 2026 Institutional Book Collection Census Dataset by Dewey Decimal Classification (DDC) Dataset Title Complete Bibliometric Profile of Burauen Community College Library: 2026 Book Collection Census by Dewey Decimal Classification (DDC) Version: 2026.1.0 (Annual Baseline Baseline) Release Date: June 2026 Data Formats Available: JSON (.json), CSV (.csv) Repository Target: Zenodo Persistent DOI Record 1. Overview & Institutional Value This dataset represents the complete cataloged book collection profile of the Burauen Community College (BCC) Library for the year 2026. This data asset serves as an empirical resource for bibliometric research, institutional resource auditing, and comparative collection analysis within academic libraries. The underlying data captures full inventory volume counts aggregated against hierarchical classifications derived from the burauenbiblio Integrated Library System (ILS) MySQL database instance. Both the DDC statistical aggregates and the tabular listings serve critical institutional functions: Collection Dominance: Identifies which academic classes and disciplines heavily dominate the active collection. Gap Analysis: Spots underrepresented categories where more curriculum resources may be critically needed. Strategic Procurement: Drives data-informed decisions for future library acquisitions, systematic inventory reviews, and annual budget planning. Accreditation Support: Demonstrates the comprehensive diversity of institutional holdings to stakeholders, academic management, and external partner institutions. Operational Efficiency: Saves significant administrative time compared to performing traditional manual catalog audits. 2. Infrastructure & Extraction Methodology The dataset is generated via the Advanced Dewey Decimal Classification Mapping engine—a core semantic feature built into the burauenbiblio platform. This subsystem executes a deterministic, 3-level interpretation process driven by three internal helper functions. These functions extract and decode raw, numerical DDC call strings step-by-step into human-readable subject categories: Main Class Extraction (Level 1): Isolates the macrohundreds discipline. Division Class Extraction (Level 2): Parses the secondary ten-digit subdivision. Topic Class Extraction (Level 3): Determines the highly specific descriptive topical classification. Evolution from Reporting to Data Export Historically, this feature was used exclusively to render a stylized "Top 30 DDC List" within the administrative analytics dashboard, leaving the remainder of the library's long-tail distribution unutilized by external tools. To facilitate broader research utilities, an extended data-export feature was introduced into the dev lifecycle of burauenbiblio. This newly engineered pipeline strips away visual UI limits, allowing the seamless extraction of the entire active classification table into universal .json and .csv streams. This complete ledger is slated for official release in upcoming burauenbiblio builds to aid institutions needing complete DDC profiles for compliance and accreditation tracking. The final dataset is compiled via the following foundational query structure: SQL SELECT ddc, classification AS main, classification_div AS division, classification_adv AS topic, COUNT(*) AS total FROM extract_ddc GROUP BY ddc ORDER BY ddc ASC; 3. Structural Hierarchy & Taxonomy Attributions To respect the strict proprietary and commercial restrictions maintained by the Online Computer Library Center (OCLC) over the full DDC schema, this system maps local library balances against open reference descriptions. The category labels used across all three mapping layers are explicitly adapted from the Wikipedia List of Dewey Decimal Classes, utilized transparently under the terms of the Creative Commons Attribution-ShareAlike 4.0 International License (CC BY-SA 4.0). Level 1 (Main Class): The primary hundreds ranges (e.g., 000 General Works, 300 Social Sciences, 900 History and Geography). Level 2 (Division Class): Structural ten-digit discipline subdivisions (e.g., 330 Economics, 950 Asian history). Level 3 (Topic Class): The granular descriptive topic corresponding to the specific decimal assignments recorded in the local catalog system. 4. Schema Definition The exported JSON and CSV formats mirror an identical, flat-file schema layout: Field Name Type Description ddc String / Decimal The standard Dewey Decimal Classification indicator recorded in the local database. main String Level 1: Human-readable Main Class category (adapted from Wikipedia CC BY-SA 4.0). division String Level 2: Human-readable Division Class discipline identifier. topic String Level 3: Human-readable Topic Class specificity. total Integer The absolute volume volume count matching this precise classification string. 5. Curation, Licensing, and Update Cadence This compilation is maintained with institutional clearance from the library administration. It represents a static annual temporal slice designed to observe year-over-year collection growth trends without introducing breaking schema changes to downstream analytics modules.

Update Policy: New collection data will be pushed as updated version stacks directly to this persistent Zenodo record on an annual basis. 6. Project Contributors & Institutional Roles This dataset is a collaborative effort between the library administration and the technical systems management team of Burauen Community College: Ramoncito R. Albay (Head Librarian - Burauen Community College) Role: Project Leader & Institutional Clearance. Oversees collection management policies and authorized the open-access publication of this dataset. Apple Grace P. Daitol (Assistant Librarian - Burauen Community College) Role: Data Curator & Cataloging Lead. Responsible for the manual and digital classification of the physical inventory, ensuring the integrity of the raw DDC assignments within the ILS. Ferdinand Tumulak (Systems Administrator / Core Dev - Burauen Community College) Role: Maintainer of the burauenbiblio ILS framework. Developed the Advanced DDC 3-level mapping helper functions, engineered the complete data-export engine, and acts as the technical repository maintainer.
