Electronic Laboratory Notebooks Douglas Perry, Ph.D. IU School of Informatics
Da Vinci’s Notebook • Ca. 1500
Curie’s Notebook • Ca. 1900
Prof. X’s Notebook • Ca. 2000
Traditional Functions of Lab Notebooks • Record experimental conditions • Store primary lab data • Note experimental observations • Give references to external data • Make interpretations • Draw conclusions • Provide legal record for intellectual property
Data vs. Metadata • Data • Raw data • Processed data • Final results • Metadata • Test conditions • Methods & SOPs • Personnel
Paper-Based Information is Limited • Hard to use • Making entries is slow, tedious • Hard to reuse • Protocols, repetitive information dropped • Easily lost • Unique documents mislaid, forgotten • Hard to search • Poor indexing, keywords, table of contents • Hard to share • Copying difficult or not legal
Paper Lab Notebooks Are Becoming Obsolete • Paper notebooks have limited capacity • Raw data is massive • Data capture is archaic • Raw printouts can no longer be stored • Data formats are restricted • 2-D gels, photomicrographs • Record-keeping is tedious • Repetitive, manual entries • Context of work is often lost • No connection to other people, projects, labs • Paper records no longer legally required • Electronic records are legal
“Closed” Notebooks Are Often Needed Source: Collaborative Electronic Notebook Systems Association
Time Spent on Data Housekeeping • Lab personnel spend >16 hr/wk managing data • Lab managers spend up to 8 hr/wk trying to find data • Proprietary information workers spend 8 hr/wk auditing notebooks Source: Collaborative Electronic Notebook Systems Association

Paper vs. ElectronicLaboratory Notebooks • Paper • Static, limited format • Passive record keeping • Can meet all legal and regulatory requirements • Electronic • Dynamic, multiple formats • Active collaboration • Can meet all legal and regulatory requirements
Paper Notebooks Vs. Knowledge Management • Knowledge is individual, not collective • Journal paradigm fosters “private” mentality • Limited collaboration with other labs, other locations • “Sharing” consists of old summaries • Difficult to supervise scientific progress of others • No easy to evaluate other’s experiments • Methods must be reinvented or reoptimized • Metadata not recorded or not traceable • Reevaluation of old data impossible • Raw data of “poor” results not kept
Unique Benefits of ELN • Integrates heterogeneous data from disparate sources • Fully searchable beyond keywords and indices • Drill-down access to raw data • Secure access from any computer • On-the-fly analysis and feedback
New Demand for ELN:21 CFR part 11 • FDA rule initiated August 1997 • Sets standards for electronic submission • Electronic records • Thoroughly validated • Automatic audit trails • Results can be recreated • Electronic signatures • Unique identity • Linked to e-record • No grandfather clause
eRecord Defined “An electronic record is any combination of text, graphics, data, audio, pictorial, or other information represented in digital form that is created, modified, maintained, archived, retrieved, or distributed by a computer system.” --21 CFR part 11.3 (b)(6)
eSignature Defined “An electronic signature is a computer data compilation of any symbol or series of symbols executed, adopted, or authorized by an individual to be the legally binding equivalent of the individual’s handwritten signature.” --21 CFR part 11.3(b)(7)

Those Who Benefitfrom ELN • Scientists • Data analysis, not data management • Lab managers • Data management, not notebook management • Compliance officers • Complete audit trails with no paper chase • QA/QC directors • Concurrent accessibility of all data • Corporate attorneys • Complete, legal records for litigation support
Concerns about ELN • Major change imposition • Restructuring of scientists’ core activities • Loss of privacy • Notebook is transformed from a personal journal to a community center • Loss of control • Data and metadata could be altered by others • Corporate imposition • Roll-out by executive fiat, not individual adoption

The Loss… • One month of work by postdoc • $3,000 in labor and supplies • Protocol to replicate experiments
The Consequences… • In effect, experiments had never been done • No preliminary data for NIH grant application • No supporting data for related publication
The Moral… • ELN is needed as much in academia as it is in industry
