THE PROJECT NOTEBOOK
The project notebook (sometimes called a field notebook) is a topic in which all
information about the project is placed. It is intended for use in the field and is the place
in which all notes, diagrams, sketches, maps, and information about the project are kept.
This is traditionally a bound topic into which additional notes, maps, and other
information are inserted and fixed. The fixing should be done with either glue or tape, not
paper clips or staples.
The most important problem with the project topic is neatness. It is good to have a
project topic be as neat as possible. In too many instances, however, workers fail to put
important data in the project topic because they are afraid that it will not be neat. They
would rather write notes on scraps of paper and then write a neat entry in the project
notebook. Sometimes people wish to write in pencil so that mistakes can be erased. It is
important both for completeness and legal reasons that none of the above be allowed.
