Other volumes seems to report page numbers correctly in URLs coming via BIBLIA.COM (note: I only checked volume 4). Volume 5 of ZEB on BIBLIA.COM consistently reports the title page for all URL entries rather than the correct page number.
This become important to me because there are some programs that are designed to use web URLs, but cannot correctly handle specialized URLs such as created by LOGOS. Thus, I can use the web based URLs from BIBLIA.COM, but not those URLs coming from LOGOS itself.
