Title: Keeping a Lab Notebook

2
What is a Lab Notebook?
  • Complete record of procedures, data, and thoughts
    to pass on to other researchers
  • Why experiments were initiated, how performed,
    and results, comments
  • Place to compile data/charts/photos/ideas
  • Place of clues, to troubleshoot problems
  • Place to observe whole picture and think
  • Legal document, to prove patents
  • Defense against accusations of fraud or lawsuits

3
Purpose of Lab Notebook
  • The purpose of a lab notebook is to keep a record
    of the experiment so you or someone else could
    repeat your work or understand exactly how it was
    done.
  • Each laboratory notebook must be written as an
    individual effort, never as a group project.

4
How Important?
  • In case of Lab Fire
  • Grab the notebooks!

5
Physical Characteristics of a Good Notebook
  • Large- gt 8.5x11 at least (attaching stuff)
  • Bound (stitched) pages to ensure integrity
  • Numbered pages
  • White gridded
  • Acid free paper (30 years)
  • Duplicate pages (differing opinions)
  • Written in Pen. Felt tip is bad.

6
Preparing a New Lab Notebook
  • Create a table of contents
  • Two facing pages
  • List experiments by
  • Title
  • Date
  • Page Number

7
Attached Materials
  • Computer generated data
  • Photographic data
  • All other data
  • Printed graphs (make as you go)
  • Datasheet templates
  • Product labels
  • Who provided plasmids, etc.
  • Notes (or pasted copies) of discussions,
    conversations, emails, readings related to expt
    design or goals
  • Archive locations of plasmids, probes, etc.
  • X-rays and other large items may be kept in a
    separate folder if they dont fit in the lab
    notebook.
  • Always write on these materials the date and
    other identifying information in case they get
    separated!

8
The importance of timing
  • Always record, update, review
  • Record as you go
  • At the LATEST, insert data the next day!
  • Do a weekly checkup
  • 1 hour to review
  • Make sure everything is attached securely, all
    summaries written, future directions written,
    record in table of contents

9
Tips to Preserve Data Integrity
  • Never, ever, remove a page
  • Fill consecutive pages
  • Cross out unused parts of pages
  • Record all info as accurately as possible.
  • Do NOT omit any result, no matter how odd.
  • Cross out mistakes lightly (might need to
    recover)
  • Write legibly
  • Put a full date (international date problems)
    with month spelled out.

10
More Helpful Tips
  • The institution owns your notebook
  • Do NOT remove your notebook from the lab (unless
    this is an acceptable lab practice)
  • You may get permission to take copies, but do
    not take original pages
  • Do NOT read another persons notebook without
    permission (even the PI wont look at advanced
    researchers notebooks secretly).
  • Should be kept for at least 5 years

11
Bad record-keeping costs.
LeMonnier, French astronomer who gets no credit
for the first sightings of the planet Uranus.
His notes were so bad that he thought it was a
comet. Discovery of Uranus is instead awarded to
Herschel. Gordon Gould had many ideas related
to the production and use of lasers. He foresaw
that they could cut steel or ignite fusion
reactions. His notes were witnessed by a
candystore notary instead of a colleague. He had
undocumented meetings with the maser people.
Years and years of legal proceedings were
required to get him some of the credit he
deserved.
12
A Proper Notebook Page
Written as the work is performed Dated and signed
by author Each section has a clear, descriptive
heading The writing is legible and grammatically
correct Active voice in first person I
added the two ingredients Read by witness and
signed/dated
13
The Right Stuff
Notebooks have to last 23 years after patent
issue. Patents take time to get, so figure 30
years longevity. Paper has to be very good (much
paper today is junk by the standards of a hundred
years ago). Notebook should be bound. No
spiral notebooks! No loose-leaf! Page layout
easy to graph, date, sign, etc. Table of
contents!
14
What to write with?
No pencils!! Erasures are a definite no-no! USE
PEN ONLY! Best bet for general use black pen.
Use other color pens for highlighting as
appropriate No white-out!! Just strike through,
explain and initial errors. Its a notebook,
not a neat book.R. Cueto (But in practice, the
neater the better.)
15
Sticky situations
  • It is better to glue or tape that original paper
    snippet into the lab book than it is to copy the
    result.
  • Glue acid-free white glue is best. I think
    this means Elmers?
  • Rubber cement is not recommended (but used to be,
    and I think it works pretty well).
  • Tape
  • Have you ever seen the 3M research complex?
  • There are various qualities of tape. Use the
    best.

16
Legal Matters
You do NOT own the notebook. Your employer
does! You may ask for a copy. Depending on the
specifics of youremployers intellectual property
agreement (usually signedby you on the first
day of employment), you may be allowed a copy.
The lab director can and should inspect books
periodically. Once a lab notebook is filled up
and no longer needed inthe lab, it is usually
kept in the company library.
17
Lab Notebook Checklist
  • Black, ballpoint pen used?
  • Legible handwriting?
  • Table of contents up-to-date?
  • Entries signed/dated (October 13, 2002 better
    than 10/13/02)
  • Clear headings saying what this page is about?
  • Written in first person?
  • Complete sentences?
  • Could the work be followed by another scientist?
  • Is the researcher correctly thinking in the
    notebook
  • Are entries witnessed appropriately?
  • Is the notebook stored safely when not in use?

18
What goes in the notebook?
  • Plans
  • Realities (deviations from the plan)
  • Observations
  • Sketches and photographs
  • Links to the notebooks of others in your group
  • Links to instrument logbooks and data on disks
  • Ideas a notebook is a repository of creativity
  • E-mails from collaborators (tape or paste them
    in)
  • Plot-as-you-go graphs do it!
  • Summaries of papers you have read
  • Hints and tips you may get from science friends
  • Concerns and personal info . but be careful
    to delineate fact from opinion. . and
    remember all info could become
    embarrassingly public!

  • Linus Pauling1954 Nobel Prize
  • One of only 4 to have won multiple
    Nobel Prizes.
  • Only one to win two in unrelated
    fields (Chemistry Peace)
  • Only one to have been awarded each
    prize without sharing.

This is a page from Linus Paulings lab notebook,
describing his discovery of the protein
alpha-helix.

EXAMPLE LABNOTEBOOK ENTRIES
The following are example lab notebook entries
graciously donated by a researcher who wishes to
remain anonymous. (Because he doesnt want
anyoneto know that he is a closet
experimentalist.) This is the type of record
keeping to which all of us aspire, but that few
manage to achieve.
