Long time exposure to teaching different Botanical science courses (Phycology, Bryopytes and Pteridophytes, Seed plants, Plant physiology and Plant Taxonomy) helped me to understand major problems related to students' learning outcomes in relation to available text books and reference materials. That in turn made me to look for approaches of solving the existing shortage of well-prepared reading materials according to the Nationally Harmonized Curriculum in areas of Botanical Sciences as well as Plant Taxonomy courses offered in Ethiopian higher learning academic institutions. Moreover, requests for text book (reading material) from my students during classroom lectures increasingly encouraged me to prepare up-to-date relevant course material that includes all course contents according to the course objectives and schedule. Moreover, it is very difficult to get such reference materials on local markets when in need. It is also difficult to buy online, whenever available, due to the expensive prices which are unaffordable or difficult other financial inconveniences.
