Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The Developer's Notebook series is modeled on the tradition of laboratory notebooks. Laboratory notebooks are an invaluable tool for researchers and their successors.

The purpose of a laboratory notebook is to facilitate the recording of data and conclusions as the work is being conducted, creating a faithful and immediate history. The notebook begins with a title page that includes the owner's name and the subject of research. The pages of the notebook should be numbered and prefaced with a table of contents. Entries must be clear, easy to read, and accurately dated; they should use simple, direct language to indicate the name of the experiment and the steps taken. Calculations are written out carefully and relevant thoughts and ideas recorded. Each experiment is introduced and summarized as it is added to the notebook. The goal is to produce comprehensive, clearly organized notes that can be used as a reference. Careful documentation creates a valuable record and provides a practical guide for future developers. Sarah Sherman was the production editor and the proofreader for Mono: A Developer's Notebook. Matt Hutchinson, Reg Aubry, and Claire Cloutier provided quality control. Angela Howard wrote the index.
