Choice of typeface

After reading a selection of books on type and printing i could make an informed choice on what typeface i would use for my book. After reading the thames and hudson manual of typography i asked myself a few question which it suggested would help determine the legibility of the type.
The what will be the information lettering them about the anatomy The why will be to learn about the anatomy of type. The who will be students. After deciding on this i could then make an informed decision about the typography and know that it would be legible and suit its intended purpose. 
For this i decided that i would use a serif font for the majority of my books as it is considered the most legible type for print as well as being appropriate for educational use as the letters have uniformity and are a good reflection of education. I choose to consider 3 serif typefaces, times new roman, adobe caslon and baskerville as they were considered the most legible type faces for print. 

As a tet to see if they would also work for my colouring images i compared the usual typeface to just the outline of the typeface to see if it was just as legible. out of the 3 typefaces i found that baskerville was the best for both as the lines were bold and that came across even without a fill. Baskervilles heavy strokes, clean, sharp lines and clear sharp serifs made this the best of the three typefaces.

As well as a serif typeface i had to choose a san serif typefaces as i knew that i would be needing to use a contrasting typeface i my designs to compare a serif letter form to. when researching i found the helvetica was popular for use in print as a san serif font as its think, bold lines with sharp curves as almost as legible as a serif font.
