Acceptance of Terms
By accessing or using the Historical Engineering Library (the “Catalogue”) at unbej.com, you agree to be bound by these Terms of Use. If you do not agree, please do not use the Catalogue. We may revise these terms from time to time; continued use after changes constitutes acceptance.
Lawful Personal Use
The Catalogue is provided for lawful personal, educational, and research purposes. You may browse, read, and download ebooks for your own use. Any commercial redistribution, resale, or systematic reproduction of content requires prior written permission. This includes, for example, incorporating ebook text into a product or service offered for sale, or republishing substantial portions of the Catalogue on another website.
Prohibited Misuse
You may not use the Catalogue for any unlawful purpose or in violation of any applicable laws. Prohibited activities include, but are not limited to: (a) attempting to disrupt, damage, or impair the Catalogue’s operation; (b) uploading or transmitting viruses, malware, or harmful code; (c) engaging in any form of harassment, fraud, or misrepresentation.
Automated Extraction and Interference
Automated tools, such as scrapers, bots, crawlers, or scripts, are not permitted to extract or harvest content from the Catalogue without express written authorization. Any activity that imposes an unreasonable or disproportionate load on our infrastructure may result in suspension of access. If you wish to use automated tools for research or analysis, please contact us to discuss possible arrangements.
Bibliographic and Transcription Limitations
The ebooks in the Catalogue are digital reproductions of historical works. While we strive for accuracy, transcriptions may contain errors, omissions, or variations from the original texts. Bibliographic metadata is provided for reference and may not be complete or current. Users should verify critical information against authoritative sources. For instance, page numbers or illustrations mentioned in editorial notes may not correspond exactly to every digital edition.
Copyright and Public-Domain Status
We make every effort to include only works that are in the public domain in the United Kingdom. However, copyright laws vary by jurisdiction, and the status of a work may differ in other countries. It is your responsibility to ensure that your use of any ebook complies with the laws of your location. Some works may contain copyrighted elements (e.g., editorial notes, new introductions) that are owned by the Catalogue or other rights holders. Where such elements are present, they are clearly indicated in the ebook description.
User Responsibility
You are solely responsible for your use of the Catalogue and for any consequences arising from that use. You agree to comply with all applicable local, national, and international laws and regulations. This includes respecting the copyright and other intellectual property rights of third parties.
Third-Party Links
The Catalogue may contain links to third-party websites or resources. These are provided for convenience only and do not imply endorsement. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites. You access such links at your own risk.
Technical Availability
We aim to keep the Catalogue accessible, but we do not guarantee uninterrupted or error-free operation. The Catalogue may be temporarily unavailable due to maintenance, upgrades, or factors beyond our control. We reserve the right to modify or discontinue any part of the Catalogue at any time without notice. We recommend that you download any ebooks you wish to keep for offline use.
Editorial Notes and Presentation
Editorial content, such as reading guides, thematic introductions, and category descriptions, reflects the views of the editor and is provided for informational and educational purposes. It does not constitute professional advice. The presentation and organization of ebooks may change over time. For example, a title currently listed under “Machines & Inventions — Reader’s Shelf” might be moved to a different category as the collection grows.
Rights-Holder Notices
If you believe that any material in the Catalogue infringes your copyright or other rights, please contact us at [email protected] with sufficient information to evaluate your claim. We will respond promptly and take appropriate action, which may include removing the material in question.
Disclaimer of Warranties
The Catalogue and its content are provided “as is” and “as available,” without any warranties of any kind, either express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. To the fullest extent permitted by law, we disclaim all liability for any loss or damage arising from your use of the Catalogue.
Limitation of Liability
In no event shall the Historical Engineering Library, its editor, or affiliates be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or data, arising out of or in connection with your use of the Catalogue, even if advised of the possibility of such damages. Our total liability for any claim shall not exceed the amount you paid (if any) to access the Catalogue.
Suspension of Abusive Access
We reserve the right to suspend or terminate access to the Catalogue for any user who violates these terms, engages in abusive behaviour, or interferes with the operation of the Catalogue. Such decisions are at our sole discretion. If your access is suspended, you may contact us to discuss the circumstances.
Service Changes
We may update, modify, or discontinue the Catalogue or any feature thereof at any time without liability. We will endeavour to provide notice of material changes, but are not obligated to do so. Significant changes may be announced on the site or via the email address you provide.
Severability
If any provision of these Terms of Use is found to be invalid or unenforceable, the remaining provisions shall remain in full force and effect. These terms constitute the entire agreement between you and the Historical Engineering Library regarding your use of the Catalogue.
