Purpose of the catalogue

The IHUAS Public Domain Literature Library exists to make historical and technical works freely accessible in a curated, reader-friendly format. The catalogue is designed for readers who wish to explore the intellectual and practical heritage of technology, industry, and science. It is not a comprehensive academic database but a selective collection that highlights works of enduring interest.

Scope and selection

The catalogue currently includes 92 books, all in the English language and sourced from Project Gutenberg. Works are chosen for their relevance to the themes of technology, invention, and industrial history. The selection spans the 18th to the early 20th centuries, with a concentration on manuals, treatises, and historical accounts. No modern works or copyrighted materials are included. The editor, Louisa Alcott, makes selections based on the availability of compelling editorial material and the work's potential to illuminate technological contexts.

Source attribution

All books are reproduced from Project Gutenberg, a reputable digital library of public-domain texts. Each record identifies Project Gutenberg as the source. The catalogue does not re-host the full texts but provides links to the original editions. No modifications are made to the content of the works themselves.

Bibliographic records

Every book entry includes the full title, author(s), publisher, subject keywords, a target reader description, and a catalogue note. The catalogue note is an original editorial commentary that summarizes the work's distinctive features, narrative voice, and structural choices. These notes are intended to guide first readings and are not substitutes for reading the works themselves. Keywords are drawn from the Library of Congress Subject Headings as provided by Project Gutenberg.

Category assignment

The 92 books are organized into four categories: Technology in Imagination, Nations Peoples & the Past, Painting Architecture & Form, and Biography & Personal Testimony. These categories are navigational aids, not definitive literary judgments. Assignment is based on the dominant theme of the catalogue note and the work's primary emphasis. Works that span multiple themes are placed in the category that best captures their overall orientation. Readers are encouraged to explore all categories for a given topic.

Editorial reading context

The catalogue notes are written from the perspective of a careful reader, not a specialist. They identify recurring images, structural patterns, and stylistic choices. The editor reads for the work's argumentative or explanatory strategy, its handling of evidence, and its implied audience. The notes do not claim to represent the author's intentions or to provide exhaustive analysis.

Edition facts and text measurements

Each work is identified by its publication date as given in Project Gutenberg metadata. Some works are later editions or reprints. The texts are unaltered; no corrections or annotations are made to the original content. The catalogue does not include page counts or word counts, as these vary across editions.

Recommendations and related works

Each category guide includes three recommended books with concrete reasons for selection. These recommendations are based on the works' representativeness, readability, and thematic interest. They are not ranked. Related works are sometimes mentioned in category notes to suggest connections between categories, but a complete cross-referencing system is not maintained.

Corrections and reader reports

Readers may contact the editor at editor@ihuas.com with corrections or suggestions. The catalogue is updated intermittently; corrections are applied when verified. There is no formal peer review or fact-checking process beyond the editor's own research. The editor relies on Project Gutenberg's text accuracy and does not independently verify every historical claim.

Public-domain limitations

All works are in the public domain under United States copyright law. The catalogue does not guarantee public-domain status in other jurisdictions. Users are responsible for verifying the legal status of works in their own countries. The library does not assert any copyright over its editorial content, which is also placed in the public domain.

Accessibility and readable presentation

The catalogue is designed for readability, using clear section headings, concise paragraphs, and plain HTML. No images, tables, or complex layouts are used. The code follows basic web standards for accessibility, though no formal conformance testing has been performed.

Independence and editorial responsibility

The IHUAS Public Domain Literature Library is an independent project. It has no institutional affiliations, no advertising, and no commercial sponsors. The editor, Louisa Alcott, is solely responsible for the content. The library does not accept submissions or solicitations. Its purpose is to serve the public's interest in historical and technical literature.

What the catalogue does not claim

The catalogue does not claim to represent every important work in the field. It does not assert that the editor has read every book in full, nor does it claim peer review, professional librarian credentials, or university affiliation. The catalogue is not a substitute for scholarly research. The category boundaries are not rigid, and the recommendations are subjective. The library does not guarantee the completeness or accuracy of Project Gutenberg's transcriptions.

Ongoing maintenance

The catalogue is reviewed periodically but is not actively updated on a fixed schedule. New books may be added as suitable works become available from Project Gutenberg. The editor may revise catalogue notes or category descriptions in response to reader feedback or new readings. No changelog is maintained.
