A better shelf starts with thoughtful sharing.

We welcome helpful, original documents with a clear purpose. These guidelines apply to document files, titles, descriptions, tags and public display names.

Share something useful

Give readers substantive information: a guide, lesson, presentation, report or original perspective. Use accurate titles, choose the closest topic, and describe what is actually inside the PDF.

Respect ownership and privacy

Upload only content you created, have permission to distribute, or that is lawfully available for redistribution. Attribution alone does not replace permission. Do not upload confidential records, passwords, financial details, private messages or personal information about others without appropriate authorization.

Keep the library safe

No malware, deceptive downloads, impersonation, harassment, sexual exploitation, unlawful material or instructions intended to facilitate harm. Do not use the platform to evade restrictions or distribute pirated books, courses or presentations.

Useful content, not link spam

Relevant citations and clearly disclosed commercial links may support a genuine document. Documents made primarily to manipulate search rankings, repeat advertisements, mislead readers or funnel them to unrelated payment pages may be rejected. Do not claim independent experience or reviews you did not have.

Review and reports

Administrators can reject, unpublish or remove material that violates these guidelines. A published document can be reported from its page. Include specific page numbers and the reason for your concern. Copyright reports should explain your relationship to the work and identify the allegedly infringing material.
