About

LibreTimes is a scientific and educational network. Authors publish long-form, structured content on a profile that doubles as their academic CV, and the people who read that work can follow it, comment on it, and get in touch.

It exists because teaching material has nowhere good to live. Preprint servers take research and not lecture notes. Institutional pages die when you change jobs. Personal sites do not render mathematics, do not carry citation weight, and do not connect to anything.

Who it is for

Lecturers, professors, teachers, and tutors publishing course material. Researchers and graduate students sharing expositions and worked problems. Students and self-learners looking for serious material. Anyone producing substantive written work in education or science.

What you publish

Content here is living: you can edit or delete it freely, and it stays at the same address. That is the opposite of a citable record, which is frozen once published, versioned, and withdrawn by retraction rather than deletion.

The types cover teaching material (lectures, seminars, tutorials, labs, problem sets), exposition (theory, talks, cheatsheets, references, popular science), and writing (essays, notes).

Everything renders the same way – Markdown with mathematics, code, diagrams, figures, and attachments – but the type drives how work is found and how it appears on your profile.

The profile is a CV

Not a social bio. Education, positions, teaching record, talks, grants, awards, skills, contacts, and researcher IDs sit alongside the work you publish, at libretimes.io/@yourusername.

Each section has its own visibility. A phone number can be private while your publication list is public, and a section you have not filled in does not appear at all.

Authors without accounts

Not every author can sign up. Profiles can exist without an account for historical figures, deceased researchers, and authors whose work was matched from external sources such as CrossRef, arXiv, ORCID, Semantic Scholar, and PubMed.

This means a lecture can properly credit Hilbert, and it means that when someone whose work was already imported does join, they can claim the profile that already describes them rather than starting from an empty one.

Works carry a provenance level – verified, imported, or self-asserted – so the difference between "we matched this from CrossRef" and "the author typed this in" stays visible.

What LibreTimes is not

Not a journal. No editorial workflow, no peer review, no acceptance bar.
Not a preprint server. Research records belong somewhere citable and frozen; see what is planned.
Not a Q&A site. Questions and answers are their own format and belong somewhere built for them.
Not a competitive-programming platform. Problems here are written to be read and cited, not scored against a time limit.
Not an interactive-lessons site. What you publish is a document, not a guided exercise.
Not an engagement product. Following, comments, and messages exist to connect people around work. Nothing ranks you for posting more often, and there is no score on a profile that a reader could mistake for standing in a field.

Licensing

Author content is CC-BY-SA-4.0 by default, and you can choose a different licence per publication. See Content licences.

The software itself is not open source. "Libre" refers to the content: free to read without an account, licensed for reuse, and exportable whenever you want it back.
