Scientists use lab books to record information about experiments. They are used to review work done in the lab, to replicate experiments, and are critical to intellectual property (IP) claims. Organisations must keep the lab books as records, but the question is asked if lab books are vital records. Because the practice of using lab books varies widely amongst scientists, a qualitative method was used to discover practices and opinions from individual scientists. Two research institutions in New Zealand were used for data collection, with nine scientists, two records managers and two IP managers being interviewed. The conclusion is that not all lab books are vital records but most of them are until they are more than 10 years old, and even then they might be necessary to support IP claims. The storage of lab books in some organisations does not match the status of lab books as vital records and needs improving, perhaps by the use of fire-resistant safes. Data saved on computers is often hard to match with experiments recorded in lab books, so the filenames and metadata links used by scientists need more standardisation. Organisations could occasionally audit the location of lab books.
