How to Reach OFUFA Catalogue
The Historical Engineering Library is maintained by a small editorial office. We welcome correspondence from readers who have taken the time to examine our catalogue and wish to share observations that may improve the collection for everyone. The most efficient way to reach us is by email: editor@ofufa.com.
When to Write
We are particularly grateful for reports concerning:
- Metadata errors — incorrect title, author, publication date, or category placement. For example, a book about shipbuilding placed under “Inventions Industry” may belong instead under “Civil Engineerings.” A note about such a mismatch helps us keep the catalogue coherent.
- File or reading issues — unreadable pages, missing illustrations, garbled text, or a format that fails to open on a specific device or browser. Please include the file format (EPUB, PDF, MOBI, etc.) and the reader software or browser version you were using.
- Accessibility problems — poor contrast, missing alt text for diagrams, or screen‑reader incompatibility. We try to follow best practices, but we rely on readers to alert us to shortcomings.
- Copyright or rights concerns — if you believe a title in the catalogue is not in the public domain in your jurisdiction, or if you hold rights to a work and wish it to be removed, please provide supporting information. We take such matters seriously and will review promptly.
- General editorial observations — suggestions for new titles, notes on the introductory essays, or thoughts on how a particular edition could be improved.
What to Include in Your Message
To help us act quickly, please provide as many of the following details as are relevant:
- The exact URL of the page where the issue appears.
- The full title of the ebook (as shown in the catalogue).
- The file format you downloaded or attempted to read.
- The device or browser you were using (including operating system and version, if known).
- A clear description of the observed problem — what you expected and what happened instead.
- If your message concerns copyright or rights, any supporting documentation (such as a link to a rights registry or a scan of a publication page) that can help us verify the claim.
Our Editorial Approach
Our catalogue is built around thematic categories such as “Mechanical Engineering,” “Electrical Technology,” “Civil Engineerings,” and “Inventions Industry.” Works like The watchmakers' hand book — Reading Notes, The evolution of the oil industry — Reading Companion, and The story of John Smeaton and the Eddystone lighthouse — Context and Discussion are presented with editorial introductions that aim to place each text in its historical and technical context. We do not claim that every ebook is public domain in every jurisdiction, and we rely on readers to help us maintain accuracy.
A Note on Privacy
If your message touches on privacy — for example, if you believe a work contains personal data that should not be publicly available — please mention that explicitly. We treat all correspondence as confidential and will not share your contact information without your consent.
Thank you for helping us keep the Historical Engineering Library a reliable resource for curious readers.
