Modern History Library is an independent catalogue of public-domain ebooks focused on war, revolution, memoir, and maritime history. We welcome correspondence that helps us improve the accuracy, readability, and accessibility of our collection.

Why contact us

Readers and researchers often alert us to matters that benefit everyone who uses the catalogue. Common reasons to write include:

• Metadata corrections — an incorrect author name, title, or date in a catalogue entry, such as a misattributed volume in a series like Domestic Annals of Scotland or a misspelled name in Washington the Soldier.
• Category placement — a title that appears in a category where it does not belong, or that is missing from a relevant section such as Sea Voyages & Shipwrecks.
• File or reader issues — an ebook that will not open, displays garbled text, or fails on a particular device or browser. This includes problems with specific formats (EPUB, PDF, Kindle) and errors in the reading experience.
• Accessibility concerns — missing alt text, poor contrast, inadequate heading structure, or other barriers that make the catalogue or ebooks difficult to use with assistive technologies.
• Privacy questions — inquiries about how we handle personal data, cookies, or tracking, if any such features are present on the site.
• Copyright or rights concerns — if you believe a title in our catalogue is not in the public domain in your jurisdiction, or if you hold rights to a work and wish to discuss its status.
• General editorial observations — thoughtful comments about the catalogue’s scope, suggestions for new additions, or feedback on the reading guides we provide for works like The Chattanooga Campaign or Four Lectures on the English Revolution.

What to include in your message

To help us act on your report quickly and accurately, please include as much of the following as possible:

• The URL (web address) of the page where you encountered the issue.
• The exact ebook title as it appears in the catalogue, and the author if shown.
• The file format you were using (EPUB, PDF, HTML, TXT, etc.) and, if relevant, the device or browser (e.g., Kindle Paperwhite, Firefox on Windows, VoiceOver on iOS).
• A clear description of the problem: what you expected to happen, what actually happened, and any error messages.
• For rights or copyright queries, any supporting information you can share about the work’s legal status in your country.

How to reach us

Please send all correspondence to the editorial team at editor@oplae.com. This address is monitored by James Atwood, Associate Editor, who oversees thematic reviews and catalogue accuracy. We read every message and consider each report carefully.

We do not provide telephone support or a postal address. Because we are a small editorial operation, we cannot guarantee a specific response time, but we aim to acknowledge receipt and address substantive reports as promptly as we can.

What happens after you write

Your report will be reviewed by the editorial team. If it concerns a metadata error or a file problem, we will investigate and, where appropriate, update the catalogue entry or replace the file. For accessibility or privacy concerns, we will evaluate the issue and make changes where feasible. If you have submitted a copyright or rights query, we will consider the information and may adjust the availability of the title in your region if the law requires.

We value the care that readers bring to this catalogue. Your observations help us maintain a trustworthy resource for everyone interested in the wars, revolutions, voyages, and lives documented in our collection.
