The Beilstein-Institut zur Förderung der Chemischen Wissenschaften (Beilstein Institute for the Advancement of Chemical Sciences) is a German non-profit foundation based in Frankfurt am Main, established in 1951 by the Max Planck Society. It carries the name of Friedrich Konrad Beilstein, whose Handbook of Organic Chemistry the institute curated for decades before that database passed into commercial hands (it lives on today as the core of Elsevier's Reaxys). Since 2005 the institute has redirected its resources into open science: two peer-reviewed diamond open-access journals, the Beilstein Archives preprint server, symposia, and open data-standard projects.

What makes Beilstein unusual among publishers is the funding model. Both journals are completely financed by the institute's endowment, so there are no article processing charges, no submission fees, and no subscription paywalls. Authors retain full copyright and publish under a CC BY license. For chemists and nanoscientists, Beilstein is one of the very few genuinely free, reputable publication venues.

2 peer-reviewed journals, both fully open access:

• Beilstein Journal of Organic Chemistry (BJOC) - established 2005. Full research papers, letters, reviews, perspectives, and commentaries across organic chemistry, from small-molecule synthesis to chemical biology. Frequent thematic issues on topics such as photoredox catalysis, mechanochemistry, and C-H activation.
• Beilstein Journal of Nanotechnology (BJNANO) - established 2010. Research across the full breadth of nanoscience: nanomaterials, nanomedicine, nanopatterning and self-assembly, nanotribology, nano-optics, and energy applications.

Both journals publish continuously (article-by-article, no issue delays), run regular open thematic issues alongside the standard stream, and are signatories of the San Francisco Declaration on Research Assessment (DORA). Both are members of the Free Journal Network.

Beilstein operates true diamond (also called platinum) open access - the model where neither authors nor readers ever pay.

All articles are published under a CC BY license, and authors retain full copyright. Because there are no fees, waiver policies and transformative (Read & Publish) agreements are simply not applicable. Articles are archived in public repositories, including PubMed Central, for long-term preservation.

• Model: single-anonymized peer review - reviewers know the authors' identities, but not vice versa.
• Criteria: manuscripts must meet Beilstein's publication criteria of high quality, originality, novelty, and importance - free does not mean unselective.
• Metrics transparency: unusually, both journals publish detailed statistics pages showing citation distributions, h5-index history, JIF, and SJR, in line with their DORA commitment.

1. Pick the journal. BJOC for organic chemistry, BJNANO for nanoscience - check the scope pages if your work sits at the boundary.
2. Prepare your manuscript. Follow the journal's Instructions for Authors; Beilstein provides downloadable templates, and formatted templates are also available on SciSpace. Beilstein journals use a numbered citation style.
3. Run the submission checklist. Each journal publishes one - covering data, graphics, and supporting-information requirements.
4. Submit via the Beilstein Publishing System. The institute runs its own submission and peer-review platform (not Editorial Manager or ScholarOne); you create an account at beilstein-journals.org.
5. Optionally post a preprint. During submission you can deposit the manuscript in the Beilstein Archives so it is citable immediately.

The Beilstein Archives is the institute's own preprint server for organic chemistry and nanotechnology. Posting is free, preprints receive DOIs, and the server is integrated with the journal submission workflow, so authors can make work public while peer review proceeds.

The Beilstein-Institut is a member of COPE, OASPA, and STM, and both journals follow COPE guidelines on misconduct and retractions. The institute also runs open-science activities beyond publishing - symposia, online talks, and data-standard projects (such as machine-readable chemistry initiatives) in chemistry and the life sciences.
