Hello, Linda! I cannot speak to your exact problem, but I have noticed similar issues when searching z39.50 in general, particularly when searching other Evergreen systems. (We don't search our own via Z39.50 except for the occasional test.)
I can tell you that Evergreen's Z39.50 ends up going through SRU (Simple Retrieval by URL). There has been a recent bug fix for Evergreen's SRU and double encoding of characters: https://bugs.launchpad.net/bugs/1431541 I just thought that I would share that information, in case you were not aware of it. Hope that helps, Jason -- Jason Stephenson Assistant Director for Technology Services Merrimack Valley Library Consortium 4 High ST, Suite 175 North Andover, MA 01845 Phone: 978-557-5891 Email: jstephen...@mvlc.org
