A lab notebook should include a description of the research problem and the solutions or hypotheses under consideration. It is particularly important to record the conception of any idea that may be new, such as an important scientific breakthrough. Conception occurs when an inventor has a complete idea of a solution to a problem. The concept should be fully described in the lab notebook, in sufficient detail such that someone of ordinary skill in your field could understand the concept. Lab notebooks should also contain experimental results and data that support your solutions or hypotheses. Each entry in the lab notebook should be complete, dated, and signed by an investigator and a witness. In addition, the title of the research project, the name of each investigator, and information about relevant funding sources should be documented on the first page of the lab notebook.
