Create 3 eBooks for epub - this refers to 3 volumes of the book with the same design, while the first volume (out of a total of 4 volumes, 3 of which are not done) is already fully prepared and serves as a complete benchmark version that meets all the requirements of most marketplaces for eBooks, and it should be used as the basis for the remaining 3 volumes of the books. The design is very simple, without any special nuances. An ideal Word file of the three volumes is needed, which can then be easily converted to epub independently without changes to the file, which is also in a format for print-on-demand in the most common unified format suitable for almost all platforms, meaning it should meet all unified parameters that are suitable for all platforms for eBook and print-on-demand versions. The first volume of the book meets all general requirements of almost all platforms - but it is still necessary to check if the book is assembled correctly in this sense - whether it corresponds to the unified scale of the platforms. (Although this was thoroughly checked during the creation of the benchmark file of the first volume)
The books have the same structure - the first volume is very simply made, it is necessary to fully adopt the formatting as in the first volume and apply it to the three remaining volumes. There are some nuances in the volumes. It is necessary to turn tables (there are few) into images - as this is a format suitable for all versions. In the second volume, formulas are images - it is necessary to convert them into typed text, taking into account the text between the formulas and the arrangement in the text and correctness of writing without errors.
Comments should be reformatted just like in the benchmark first volume, as well as everything else. It is necessary to check in the final files of the completed 3 volumes that no comments, words, or anything else is missing.
In total, there are 3 volumes of books, simply typed in Word with approximately 500,000 characters in each volume, excluding spaces.
Some of the features:
It is important that comments to links are not broken but are continuous text - comments are absolutely as important in writing and formatting as the main text.
It is necessary to provide all the parameters, sizes, distances, fonts, and others used in creating the electronic versions of the books and the print version - what and how was used and established. (For subsequent work on other eBooks)
All nuances can be discussed further and a final decision made.
