Some iPad Textbooks Weigh In Above Apple"s 2GB Book Size Limit

Cult of Mac took a look at the size of the digital textbooks available on iBooks after today"s education-focused media event. File sizes range from Pearson"s 793MB Environmental Science up to a hefty 2.77GB for Biology.
- Pearson’s Environmental Science – 793MB - National’s Chemistry – 959MB - E.O. Wilson’s Life On Earth – 965MB - McGraw Hill’s Algebra 1 – 1.09GB - McGraw Hill’s Geometry – 1.22GB - McGraw Hill’s Physics – 1.25GB - McGraw Hill’s Biology – 1.49GB - Pearson’s Biology – 2.77GB
For regular authors, Apple limits the file size of books created with the iBooks Author app to 2GB -- something that Pearson"s tome easily exceeds. Unsurprisingly, major publishers get to bypass limits that the average author must abide.
