Electronic lab notebook
An Electronic Lab Notebook is a digital software program designed to replace paper laboratory notebooks, allowing researchers to document experiments, store data, and collaborate.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
Ensuring Data Integrity and Compliance
A key advantage of ELNs over paper notebooks is their ability to enforce data integrity. High-quality ELNs include audit trails that log every edit, deletion, and file upload, showing who made changes and when. Under regulatory frameworks like FDA 21 CFR Part 11, these features—combined with digital signatures and timestamping—provide the legal proof of discovery needed for patent applications and compliance reviews. This digital audit trail prevents retrospective modification of research results, protecting intellectual property and building trust in scientific findings. Researchers use this system to document experiments chronologically, providing clear evidence of their methods. In clinical trials, compliance with these data standards is mandatory, and ELNs ensure that all raw data remains unaltered, verified, and ready for regulatory audits.
Collaboration and Standardisation in Lab Groups
ELNs improve laboratory efficiency by serving as a shared database of protocols and results. Principal investigators can oversee project progress in real-time, review lab members' entries, and sign off on experiments. Standardised templates ensure that all lab members document metadata, instrument settings, and sample codes consistently, reducing errors and making onboarding easier. Team members can share procedures and link observations to samples, ensuring that everyone has access to the latest protocols. This collaborative workspace reduces duplication of effort and improves data consistency across the research group. In addition, when students leave a project, their digital notes and data remain organised and accessible within the institutional system, preventing the loss of knowledge that often happens with paper notebooks.
Key Selection Criteria for Research Institutions
When choosing an ELN, institutions must evaluate security, compatibility, and exportability. The platform must support the specific data types used by the lab (e.g., chemical structures, genomic sequences) and integrate with laboratory information management systems (LIMS). It must also support open export formats (like PDF/A or XML) to ensure data remains readable if the software provider closes. Institutions must compare open-source tools (like eLabFTW) with commercial solutions (like Labfolder or Benchling) to assess licensing costs, security features, and customisation options. The chosen ELN must meet local data residency rules and support offline work in remote sites. Ensuring these requirements are met before purchase protects long-term research data accessibility and supports institutional compliance with public funding requirements.
Key facts
At a glance
- It digitises laboratory note-taking, protocol documentation, and raw data storage.
- Audit trails and cryptographic timestamps prevent retrospective editing.
- Standardised templates ensure consistent metadata and procedure recording.
- It supports compliance with regulatory standards like FDA 21 CFR Part 11.
- Export options like PDF/A ensure long-term readability and archiving.
Common misconceptions
What people often get wrong
Often heard: A Microsoft Word document or a simple shared folder is a compliant ELN.
Actually: Word docs lack audit trails, digital signatures, and permanent timestamps, which are legally required for regulatory compliance and patent protection.
Often heard: Using an ELN makes your proprietary laboratory data vulnerable to hacking.
Actually: Reputable ELNs employ high-level encryption, multi-factor authentication, and comply with institutional security policies, often offering more secure storage than physical notebooks.
Common questions
FAQ
What is FDA 21 CFR Part 11?+
It is a regulation defining the criteria under which the FDA considers electronic records and signatures to be trustworthy, reliable, and equivalent to paper records.
Can I draw chemical structures in an ELN?+
Yes, many scientific ELNs integrate drawing tools (like ChemDraw) to let researchers sketch and search chemical structures and reactions directly within entries.
