STEP Library
STEP Library or STEP is a standard that was embraced by multiple software developers for Biblical software libraries, primarily throughout the mid to late 1990's. STEP is an acronym for Standard Template for Electronic Publishing. If a book or reference work is compatible with STEP Libraries, it was said to be STEP-Compatible. STEP is a trademark of previously Parsons Bible Software, now of Findex, the publisher of Quickverse Bible Software.
While not open format, the availability for outside licensing and publishing makes it similar to the The Libronix Digital Library and the Pradis systems, especially for users of religious software who want seamless integration of various reference works, using one application to access and cross-reference them all. Further, by limiting duplicate applications running or loaded, system registries are kept cleaner, more works can be open and cross-referenced simultaneously, and Harddrive space is conserved.
Examples
Examples of Study Bible software libraries that can read STEP modules include e-Sword, and late 1990's versions of Zondervan Software.
