Contact the catalogue project
Classic Science Fiction Archive is maintained by a single catalogue project. Your observations help keep the catalogue accurate and readable. Below are the most useful reasons to write, along with guidance on what to include so your message can be acted on promptly.
When to get in touch
- Metadata corrections — If a title, author name, or publication date appears incorrect, or if a work is placed in a category that seems wrong (for example, a story listed under Machines Invention that belongs in Social and Psychological Fiction), please send a note. The same applies if you notice a duplicate entry or a missing work that should be in the catalogue.
- Unreadable files or reader failures — If a download fails, a file is corrupted, or a format (EPUB, PDF, MOBI, etc.) does not open properly on your device or browser, describe the problem in as much detail as you can. Including the exact error message helps a great deal.
- Accessibility issues — If a file lacks proper headings, alt text, or semantic structure, or if your assistive technology cannot navigate it, your report is especially valuable. The goal is to make every ebook usable with screen readers, text-to-speech tools, and other assistive software.
- Privacy questions — Although the site does not collect personal data or use tracking cookies, you may ask about how your visit is handled. No data is shared with third parties. If you have concerns about any embedded content, please let us know.
- Copyright or rights concerns — If you believe a work in the catalogue is not in the public domain in your jurisdiction, or if you hold rights to a text and wish to discuss its inclusion, please provide any relevant documentation. The catalogue aims to include only works that are clearly in the public domain, but copyright laws vary by country.
- General editorial observations — Typographical errors, missing illustrations, inconsistent formatting, or suggestions for additional reading notes are always welcome. For example, if a reading companion like The Seeder — A Closer Reading contains a factual mistake or could be improved, your feedback is appreciated.
What to include in your message
The more context you provide, the faster the issue can be investigated. Please include:
- The exact page URL (the address in your browser’s address bar).
- The full ebook title and, if possible, the author’s name.
- The file format you are using (EPUB, PDF, MOBI, HTML, etc.).
- The device or browser you are using (e.g., Kindle Paperwhite, Firefox 120, Adobe Digital Editions).
- A clear description of the observed problem. For unreadable files, mention any error messages you see.
- If your message concerns copyright or rights, include any supporting information you are able to share.
