The planned digital textbook Human Parasitology， the first of its kind， published by People's Medical Publishing House is an important medical education effort that features the inte-gration of digital resources. This paper introduces the digital textbook construction goal， namely using paper-based textbook for five-year undergraduates as blueprint to reasonably display the digital re-sources based on the features of the discipline. The advantages of this digital approach over traditional paper-based textbook in demonstrating parasitic morphology， lifecycle， pathogenesis， diagnosis， epi-demiology and control are discussed. Valuable experiences in planning and constructing this digital textbook are to be shared.
