As a compiler of a number of Libronix PBB resources, my first foray into building PBBs in Logos 4 has been largely positive. I did a test compiling chapters of John Donne's "Devotions Upon Emergent Occasions" and E.W. Hengstenberg's commentary on Ezekiel. These files were original filtered and tagged HTML files brought into Word and saved as .docx. I did no further editing of the files. Here are my initial observations:
1. Hebrew text comes in nicely, with pointing intact.
2. Formatting is pretty much spot on.
3. Logos 4 does not create footnotes. It does not seem to recognize the text tags of the footnotes.
4. Bible verses show up just fine if the verse is in a convention recognized by the compiler (e.g. Psa. 1:1, Luke 1:1, etc.) However, verse references I had to individually tag because they would not be recognized by the compiler (e.g. Vers. 16, etc. -- which I tagged to point to a specific reference) does not work.
5. It appears that an entire book must comprise one source file, not many. Building PBBs in John McComb's Builder Builder for Libronix required that I create individual files for each chapter in a book. This is a different process in Logos 4. In Libronix, when I compiled a PBB, there could be many source files.
6. Converting the source HTML files in Word strips out the links which I used for the TOC.
So, I am impressed so far, but those of us who have a lot of source HTML files will have to do some work for these to be compiled in Logos 4.
