I've heard the following:
Most of the good materials out of copyright that can be distributed freely have already been done;
The source materials for many works are so poor or incomplete that they are difficult or impossible to use;
Permissions were denied on many good materials still in copyright.
"Good" in many cases is strictly a 'subjective' term, similar to the difference betwixt 'meat' and 'milk'. There are literally hundreds of texts available to be processed into eSword modules, but the effort to transform these texts is more than most people are willing to expend.
Perhaps 'value' or how a person values an eSword module would be one perspective. Transforming an old text of a missionaries biography doesn't seem to have much value when compared to a commentary, except for the young believer wondering how he may serve Christ amongst non-believers (which are increasing daily). Apologetics and Islam is another group of modules missing. Vast numbers of hymnals are available to feed the hungry hearts for those willing to sit down and transform them. Then, of course, there are the many "Complete Works of ___ (fill in the blank)" available.
Acorns grow into mighty oak trees, given half the chance....
As highly as I might esteem myself, I find that I am NOT the Holy Spirit. At best, I'm merely something God may choose to use. Likewise, God might choose to use the author of any book I would transform into an eSword module. His tool, His choice. I've not been given permission to change syntax or intent, rather just transcribe the authors verbiage. I can be assured that the Holy Spirit will only use those things which promote the work of Christ on the readers heart.
