Opac complainers l.jpg
“OPAC Complainers”

“There is certainly no dearth of OPAC complainers. You have Andrew Pace (OPACs suck), and Roy Tennant (You Can’t Put Lipstick on a Pig) writing and presenting about the need for change (more simplicity) in the OPAC world. I can appreciate their arguments for a simpler OPAC (not to mention the rest of the system) but other then present their arguments, neither has much in the way of suggestions nor have they sparked a movement among librarians or the automation vendors to do anything about the situation.”

    Charge:

    The implementation group is charged to:

  • Review the documentation, software, and consult with Endeca implementation consultants to determine the range of issues associated with implementing Endeca ProFind

  • Work with Endeca QuickStart team on facilitating site visit to determine functional requirements to prepare their Technical Specifications document

  • Advise on integration and interface issues with Sirsi Unicorn

  • Facilitate librarywide review of interfaces; conduct usability testing
