# Lab Group Protocols for Shared Notebooks By the end of this article you will be able to draft a [lab notebook](/knowledge/molecular-biology/lab-notebook) sharing SOP for your research group, choose between a paper notebook and an electronic lab notebook for shared work, set up a notebook structure with sensible permissions, write entries that another scientist can reproduce, and run a monthly audit that catches problems before they become data integrity issues. To follow the walkthrough you need an account on an electronic lab notebook (ELN) platform or a controlled shared drive, a list of your group members and their roles, and a copy of your institution's data retention and intellectual property policies. ## Why Shared Notebooks Need a Written Protocol A lab notebook exists to prove what was done, when, by whom, and why. In a solo project a single well-kept notebook can carry that burden. The moment two or more people write into the same record system, informal habits stop working. Someone edits an entry another person already signed. A protocol file gets overwritten. A departing student leaves data scattered across personal folders that nobody else can read. A standard operating procedure, or SOP, is the short written document that prevents those failures by stating exactly who may write where, what every entry must contain, and how changes are recorded. The case for a written protocol is stronger today because experiments generate more data than paper can hold. Electronic lab notebooks are better equipped than paper lab notebooks to handle modern life science experiments that produce large data sets and demand high levels of data integrity [1]. Cloud-based ELNs also allow real-time and remote monitoring of experiments, quick archiving, and simpler information exchange between group members, which is precisely the workflow a shared notebook protocol has to manage [1]. Yet many academic labs still rely on paper records, partly because training in electronic record keeping and good documentation practices has lagged behind adoption [1]. A lab notebook sharing SOP closes that gap by writing the rules down so every new member learns them the same way. ## Key Terms in Plain Language Before drafting your SOP, make sure every group member uses these words the same way. Your SOP should include a definitions section that repeats them. - **ELN (electronic lab notebook)**. Software that records experiments digitally, usually in the cloud, with search, sharing, and time-stamped records. - **PLN (paper lab notebook)**. A bound physical notebook, traditionally the default record in life science labs. - **SOP (standard operating procedure)**. A controlled written document that specifies how a recurring task must be performed. - **GDP (good documentation practices)**. The habits that make a record trustworthy, such as dating entries, signing them, and correcting errors without erasing the original. - **Audit trail**. An automatic, time-stamped log of who changed what and when. A capable ELN includes an audit trail as a core feature alongside a permissions system, controlled sharing, electronic signature, and search [2]. - **Electronic signature**. A signed, attributable, time-stamped confirmation that an entry is complete and accurate. - **Permissions system**. The access rules that control who can read, write, edit, or approve each section of a notebook. - **Version control**. The practice of keeping every revision of a record rather than overwriting the previous one. - **Metadata**. Structured information about a record, such as date, author, project, and instrument ID, that makes entries findable years later. ## Choosing a Platform: An Electronic Lab Notebook Comparison An electronic lab notebook comparison should start from capabilities rather than brand names. Research into ELN design identified a clear baseline of features a shared scientific notebook needs: a permissions system, controlled sharing, an audit trail, electronic signature, and search, all presented through an interface that reads like the electronic counterpart of a paper notebook [2]. When you evaluate any platform, check each of those five capabilities in a trial account and confirm they work at the level of an individual entry, not just a whole notebook. Two practical points from real deployments are worth building into your decision. First, ELNs succeed in teaching and research settings when the platform supports streamlined workflow, quick data recording and archiving, and enhanced data sharing and collaboration, and when users receive structured training rather than being handed an account with no guidance [1]. Budget time for onboarding in your SOP. Second, a shared notebook is more than an experiment log. Groups that adopt ELNs use them to compile the diverse collections of data biologists generate, such as images and spreadsheets, and even to take minutes of meetings [2]. Your SOP should therefore define sections for protocols, meeting notes, and shared reagent or sample inventories, not just raw results. For groups required to operate under formal quality or regulatory frameworks, confirm with your institution that any platform you choose supports electronic signatures and audit trails in a form your compliance office accepts. Student and trainee responses in an academic deployment indicated that an ELN was better than paper for compliance [1], but the acceptance decision belongs to your institution, not the platform vendor. The table below summarizes the capability checklist to score any candidate platform during your comparison. | Capability | What to verify in a trial | Why it matters for a shared notebook | |, - |, - |, - | | Permissions system | Individual users can be granted read-only, write, or approve rights per notebook or per section | Prevents accidental edits by people who only need to read | | Controlled sharing | Sharing links and access can be granted, scoped, and revoked | Lets you collaborate outside the group without losing control | | Audit trail | Every create, edit, and delete action is logged with user and timestamp | Preserves the record of how data changed over time | | Electronic signature | A user can sign an entry as complete, with the signature tied to their account and a timestamp | Supports good documentation practices and review workflows | | Search | Full-text search across entries, attachments, and metadata | Makes prior experiments findable without asking the person who did them | | Attachment handling | Images, spreadsheets, and instrument files store and preview correctly | Biology data is heterogeneous, so the notebook must hold more than text | | Export | Entries and attachments export in a non-proprietary format | Protects the group against platform shutdown or lab migration | ## The Lab Notebook Sharing SOP Format A usable lab notebook sharing SOP format is short enough that people actually read it. Aim for four to six pages. Use the following section order, which mirrors the format taught in good documentation practice training. 1. **Title, document number, version, effective date, and review date**. Every SOP carries these so nobody follows a stale version. 2. **Purpose and scope**. One or two sentences on what the SOP controls and which people, projects, and notebooks it covers. 3. **Definitions**. The terms listed above, plus any platform-specific terms your group uses. 4. **Roles and responsibilities**. Who owns each notebook, who reviews entries, who administers permissions, and what the principal investigator is responsible for. 5. **Notebook structure and naming conventions**. The fixed section layout and the file and entry naming rules. 6. **Entry requirements**. The minimum content of every entry, described below. 7. **Review, signing, and witnessing**. When entries are signed, who reviews them, and on what schedule. 8. **Corrections and version control**. How to amend a signed entry without destroying the original record. 9. **Storage, backup, and export**. Where master records live, how often they are exported, and where exports are kept. 10. **Onboarding, offboarding, and archival**. Training for new members, access removal for departing members, and the retention period for closed notebooks. The entry requirements section is the heart of the document. Every experiment entry should contain, at minimum, the date and time, the full name of the person performing the work, the aim of the experiment in one sentence, the exact protocol or protocol version used, reagent and lot numbers where identity matters, instrument IDs, raw data files by name, observations and deviations noted in real time, and the signature block. Deviations deserve special wording in your SOP. A deviation is any departure from the written protocol, and the correct practice is to record it in the entry at the time it happens, with a reason, rather than silently fixing the protocol after the fact. ## A Lab Notebook Sharing SOP Template The following lab notebook sharing SOP template is a working example you can adapt. Replace the bracketed placeholders with your group's details. This skeleton plus the walkthrough in the next section gives you a complete lab notebook sharing SOP example in under an hour of editing. ```text STANDARD OPERATING PROCEDURE Title: Shared Lab Notebook Use Doc number: SOP-LNB-001 Version: 1.0 Effective date: [DATE] Review due: [DATE + 1 YEAR] 1. PURPOSE AND SCOPE This SOP defines how members of the [GROUP NAME] record, share, review, and archive experimental work in the group's [PLATFORM] shared notebook. It applies to all members, visitors, and collaborators who write to or read from the shared notebook. 2. DEFINITIONS ELN, PLN, GDP, audit trail, electronic signature, permissions, version control, metadata, deviation (as defined in group training). 3. ROLES AND RESPONSIBILITIES Principal investigator: approves this SOP, grants notebook ownership. Notebook owner ([NAME]): maintains structure, checks compliance monthly. Reviewer ([NAME]): reviews and signs completed entries weekly. All members: create entries per Section 5, request signatures when done. 4. NOTEBOOK STRUCTURE Section 01 Protocols Section 04 Meeting notes Section 02 Experiments Section 05 Reagents and samples Section 03 Instrument logs Section 06 Archive (closed projects) 5. ENTRY REQUIREMENTS Every experiment entry must contain: date and start time, author's full name, one-sentence aim, protocol name and version, reagent lots where identity matters, instrument ID, raw file names, real-time observations and deviations, and a signature request on completion. 6. NAMING CONVENTION Entries: YYYY-MM-DD_short-title_INITIALS Files: YYYYMMDD_EXP-###_description_v#.ext Examples: 2026-11-11_miniprep-pSmad3_JA 20261111_EXP-011_gel-image_v1.tif 7. REVIEW, SIGNING, AND WITNESSING The author requests an electronic signature when an entry is complete. The reviewer signs within business days. Critical entries, defined as those supporting a publication figure or a regulatory submission, also require a witness signature. 8. CORRECTIONS AND VERSION CONTROL Signed entries are never deleted. Errors are corrected through the platform's amendment function, which records who changed what and when. The reason for the amendment is written in the amendment comment. 9. STORAGE, BACKUP, AND EXPORT The [PLATFORM] notebook is the master record. The notebook owner exports all entries and attachments to [LOCATION] on the first business day of each month and confirms the export opens correctly. 10. ONBOARDING, OFFBOARDING, AND ARCHIVAL New members complete ELN training and read this SOP before receiving write access. Departing members export their entries, transfer ownership of in-progress work, and lose access on their last day. Closed notebooks move to Section 06 and are retained per [INSTITUTION] policy. ``` ## Setting Up a Shared Notebook, Step by Step ![Flow from assigning roles through building sections, loading protocols, publishing a template, setting permissions, and monthly audit and export.](/article-images/illustrations/lab-notebook-sharing-sop-setup-steps.webp) This walkthrough assumes a cloud-based ELN with a permissions system, audit trail, electronic signature, and search, the feature set developed for shared research use in early online ELNs and now standard across platforms [2]. Adapt the commands and names to your platform. **Step 1. Inventory your people and roles.** List every person who will touch the notebook and assign one of four roles: owner, writer, reviewer, or read-only collaborator. One person can hold two roles, but only the owner should change the notebook structure. **Step 2. Create the notebook and its fixed sections.** Build the six sections from the template above. Fixed sections matter because search only helps if everyone files entries in a predictable place. Do not let members invent personal subfolders inside the Experiments section. **Step 3. Load your protocols first.** Before anyone logs an experiment, enter each standing protocol into Section 01 with a version number. Entries will then reference protocol versions instead of retyping procedures, which keeps entries short and makes protocol changes traceable. **Step 4. Publish an entry template.** Create a reusable lab notebook template so every experiment entry starts with the same header. Most ELNs support templates. If yours uses Markdown or plain text, this header works well: ```text title: 2026-11-11_miniprep-pSmad3_JA date: 2026-11-11 author: J. Alvarez project: pSmad3-expression experiment_id: EXP-2026-011 protocol_used: P-SOP-007 miniprev4 v2.1 status: draft signed: false witness: none deviations: none ``` Expected result in your platform's entry editor: the header appears at the top of every new entry, the status field reads `draft`, and the signed field flips to `true` only after review. The `experiment_id` ties the entry to related entries, for example a pilot run numbered `EXP-2026-009`. **Step 5. Enforce the naming convention with a check, not a memo.** Write the naming rule into the SOP, then verify it mechanically. If your attachments live in a synced folder, a single command finds violations: ```text $ find shared-notebooks -type f ! -name "20*" -print shared-notebooks/experiments/pcr-master-mix-final.docx shared-notebooks/meetings/notes-week3.txt ``` Expected output: any file whose name does not start with the year appears on screen. Two violations found in this example need renaming to `20261111_EXP-011_pcr-master-mix_v2.docx` and `20261109_meeting-notes-week3_KT.txt`. Run this check monthly and paste the output into the owner's log entry. For platforms with their own file stores, perform the same check visually during the monthly review. **Step 6. Configure permissions to match the roles.** Grant writers access to Experiments, Instrument logs, and Meeting notes. Grant read-only access to collaborators and to the Protocols section, so protocols change only through version-controlled updates by the owner. Set the reviewer's account to approve but not author. Confirm the audit trail is enabled platform-wide before anyone writes, because a record created before auditing starts has no change history. **Step 7. Define the review and signing loop.** The author completes an entry, fills the header, and requests an electronic signature. The reviewer opens the entry, checks the protocol version against Section 01, checks that raw file names exist, and signs. The signature is time-stamped and attributable, which is what converts a draft note into a formal record [2]. Set the review window at five business days so entries never pile up unsigned. **Step 8. Write the correction procedure down and test it once.** When a signed entry contains an error, the author adds an amendment through the platform's revision function, states the reason in the amendment comment, and leaves the original text recoverable in the version history. Run a deliberate test amendment during onboarding so people see the audit trail record it produces rather than discovering the mechanism under pressure. **Step 9. Train every member and log the training.** A real academic deployment of a cloud ELN found that user experience scores improved between the first and second years the platform was offered, driven by structured training and iterative fixes to the training itself [1]. Treat your first semester as a pilot. Hold a 30-minute session, have each member create and sign a practice entry, and record who completed training in the notebook itself, which turns onboarding into part of the record. **Step 10. Run a monthly audit and export.** On the first business day of each month the owner performs three checks. First, run the naming check from Step 5. Second, confirm every entry marked complete carries a signature. Third, export the full notebook with attachments to your institutional archive and open one random export file to confirm it is readable. Log the audit as a dated entry. This habit catches drift early and gives you a defensible archive even if the platform changes. ## Common Mistakes and Limitations - **Treating the ELN as a backup instead of the master record.** If members keep the real data on personal laptops and copy summaries into the notebook, the shared notebook proves nothing. The SOP must name the notebook as the single master record and require raw files to be attached or referenced by ID. - **Skipping the audit trail at setup.** Some platforms allow auditing to be toggled per notebook. If the first weeks of work occur before auditing is switched on, those entries have no change history and cannot be reconstructed. Enable auditing before the first entry. - **Blanket write access.** Giving every collaborator full rights seems friendly and causes the classic failure: someone edits a signed entry. Match permissions to the role list and revisit them whenever someone joins or leaves. - **No training plan.** Limited training and a shortage of people fluent in ELN record keeping are the documented reasons academic labs stick with cumbersome paper notebooks [1]. A notebook nobody knows how to use correctly is worse than a paper one, because errors hide inside a system that looks official. - **Naming convention drift.** Conventions decay within weeks unless checked. The monthly find command or visual check is what keeps the convention alive, not the SOP document itself. - **Silent protocol edits.** If someone improves a protocol and starts using it without incrementing the version in Section 01, past entries now reference a protocol that no longer matches. Require a version increment and a dated note for every protocol change. - **Deleting instead of amending.** Deleting a bad entry, even an accidentally duplicated one, breaks the record chain. Amend, annotate, and preserve. - **Assuming the platform will exist forever.** Vendor products change or shut down. The monthly export in Step 10 is your insurance, and the export must be in a format your institution can open without the vendor's software. One limitation deserves plain statement. This article gives you the structure and mechanics of a shared notebook protocol, but your institution's policies on data ownership, retention periods, intellectual property, and biosafety take precedence over any generic template, and specific projects may carry additional requirements set by your principal investigator, your funding agency, or your compliance office. Confirm those local rules before you finalize version 1.0 of your SOP. ## Frequently Asked Questions ### What is a lab notebook sharing SOP? A lab notebook sharing SOP is a short controlled document that defines how a research group records, shares, reviews, corrects, and archives work in a common notebook, covering roles, permissions, entry content, naming, signing, and retention. ### Can I use this SOP template for a paper notebook instead of an ELN? Yes, most sections transfer directly, but you will need paper-specific rules for page numbering, permanent ink, witness signatures, and photocopying, since paper cannot provide an automatic audit trail, search, or remote access. ### Who owns the data in a shared lab notebook? Ownership and intellectual property rights are set by your institution's policy and, in some cases, your funding agreements, not by the notebook platform, so the SOP should name the institutional owner rather than declaring one. ### Can two people edit the same notebook entry at the same time? Many cloud ELNs support concurrent editing with each change attributed to its author, but concurrent editing of a single experimental entry is poor practice, so your SOP should assign each entry to one author who requests a signature when done. ### How often should shared notebook entries be reviewed and signed? A practical default is completion of each entry by the author on the day of the work and review by a designated reviewer within five business days, with witnessed signatures for entries that support publication figures or formal submissions. ### What is the difference between an ELN and a paper notebook for sharing? ![Comparison table of electronic and paper lab notebooks across audit trail, search, signatures, sharing, and large data files.](/article-images/illustrations/lab-notebook-sharing-sop-eln-vs-paper.webp) An ELN offers search, controlled permissions, automatic audit trails, electronic signatures, remote access, and easy attachment of large data files, while paper requires physical presence, manual witnessing, and separate storage for digital data. ### Do shared electronic notebooks satisfy data integrity requirements? ELNs with audit trails and electronic signatures support strong data integrity and trainees rate them better than paper for compliance, but formal acceptance depends on your institution or regulatory context, so confirm the platform with your compliance office before committing. ### How much time does setting up a shared notebook system take? For a typical academic group, drafting the SOP from the template takes about an hour, platform configuration and template setup take another hour or two, and the main ongoing commitment is a monthly audit and export of roughly 30 minutes. ## Sources 1.
