International Open Access Week  highlights the move toward breaking down barriers and sharing knowledge with the greater community through open access publications. This year’s theme, Community over Commercialization, encourages a candid conversation about which approaches to open scholarship prioritize the best interest of the public and the academic community, and which do not.

In celebration of International Open Access Week, join us in exploring the many ways microbial science research is becoming more accessible and equitable. Explore our latest open science principles, policies and compliance with the latest open access mandates. Plus, read about ASM’s movement toward Subscribe to Open (S2O) in 2025.

Our Continued Commitment to Open Access

The American Society for Microbiology’s (ASM) mission is to advance the microbial sciences. Every day we, as a Society, take steps to do just that, including announcing our recent membership into the Alliance for Open Science. We will adopt a Subscribe to Open model for our 6 primary research, subscription-based journals in 2025 by following the process below. This aligns with our mission to share high-impact research with a global audience and accelerate scientific advancement. With S2O, making our subscriber-only content open access would depend on the continued support of subscribers. Each year, we will set the minimum sustainability target to fund the journals. If subscriptions reach the target, that year’s subscriber-only content will be made open access. If that target is not reached, then subscriber-only content will be available to subscribers only.

Our 6 Open Access Journals

Journal of Microbiology & Biology Education® (JMBE) ASM’s first open access educational journal is dedicated to publishing articles rooted in the biological sciences that address topics such as good pedagogy and design, student interest and motivation, recruitment and retention, citizen science and institutional transformation. Read the full scope to learn more about JMBE.

mBio® ASM’s top broad open access journal publishes the best papers in all disciplines that address microbiological problems, including, but not limited to, biochemistry and molecular biology, genetics and genomics, environmental science, evolution, immunology, infectious disease and physiology. Read the full scope to learn more about mBio.

Microbiology Resource Announcements® (MRA) publishes articles announcing the availability of any microbiological resource deposited in a repository available to the community. Read the full scope to learn more about MRA.

Microbiology Spectrum® (SpectrumASM’s newest open access journal publishes research from all domains of basic, applied, and clinical microbial sciences. Rather than making subjective evaluations of potential impact, it publishes research studies that are of high technical quality and are useful to the community. Read the full scope to learn more about Spectrum.

mSphere® is a multidisciplinary open-access journal that focuses on rapid publication of fundamental contributions to our understanding of microbiology. Its scope reflects the immense range of fields within the microbial sciences, creating new opportunities for researchers to share findings that are transforming our understanding of human, animal and plant health and disease, ecosystems, neuroscience, energy production, climate change, evolution, biogeochemical cycling and food and drug production. Read the full scope to learn more about mSphere.

 mSystems® publishes preeminent work that stems from applying technologies for high-throughput analyses to achieve insights into the metabolic and regulatory systems at the scale of both the single cell and microbial communities. Read the full scope to learn more about mSystems.
