Keeping Laboratory Notebooks

Why is a laboratory notebook so important?

  • It is a complete ‘legal’ document.
  • A recording of your work in the laboratory.
  • Vital in proving you conducted the research.
  • Invaluable in proving the right to ownership of a patent before dates of prior art.

The notebook:

  • Pages should be permanently sewn or otherwise bound to the book.
  • DO NOT use loose-leaf folders or ring bound notebooks.
  • Pages should be numbered consecutively.
  • No pages or spaces should be skipped. If so a line should be drawn through them to demonstrate the spaces are intentional and avoid misinterpretation.
  • Legible entries in indelible ink. Never use pencils.
  • Errors must remain legible i.e. lined out rather than erased or covered.
  • The integrity of the record should not be questionable.
  • Entries should be in chronological order, without blank pages.
  • Never tear or destroy pages.
  • Additional information including diagrams and photographs should be dated and attached via stapling or adhesive.
  • Ideally these should be signed and dated by the researcher across the document and the underlying page.

How much detail?

  • Your notebook is just that a NOTEbook!
  • Err on the side of thoroughness and completeness.
  • Should contain enough information so that a technically informed third party will understand what was done without the assistance of the researcher who made the entries.
  • Include an index and glossary defining trade names, acronyms, codes etc at the front of the notebook.
  • Include all results be they positive or ‘negative’. Remember everything goes into a thesis/publication.
  • Enter batch/lot numbers of items used in experiments.
  • Do all calculations in the notebook, DO NOT use separate loose sheets.
  • Discuss with supervisor about signing off on work in notebook.

Ownership:

  • All notebooks are the property of RCSI. When you leave, your notebooks remain in college with your supervisor.
