Pursuing my intention (in the previous post) of adding my highlighted text selections to the front of an existing e-book, I looked into the work-around of merging two e-book files, the first containing my excerpts (saved as a separate file) and the second containing the original e-book.
On searching I found the following:

Merging files
Sometimes, you may want to merge two HTML files or two CSS files together. It can sometimes be useful to have everything in a single file. Be wary, though, putting a lot of content into a single file will cause performance problems when viewing the book in a typical ebook reader.
To merge multiple files together, select them by holding the Ctrl key and clicking on them (make sure you only select files of one type, either all HTML files or all CSS files and so on). Then right click and select merge. That’s all, calibre will merge the files, automatically taking care of migrating all links and references to the merged files. Note that merging files can sometimes cause text styling to change, since the individual files could have used different stylesheets.
======================================
Consequently, I converted the two epub files to html, selected them in Calibre as instructed above, and right-clicked on the selection. Unfortunately, there was no option to merge the two files, as the help article stated would be the case.
Am I doing something wrong? Am I misinterpreting? Are the help instructions applicable? Is there another way to accomplish this?
Thank you for any help.
