Hello, First, I would like to offer a belated thanks to Ian, Nora, and Brooke for helping me out with my 952 $o problem a few weeks ago. With their help, I found a regular expression that moved the LC call numbers to $o. Now I have run into a new challenge. I *think* I have gotten my 952 holdings statement correct, and have staged & successfully imported my MARC records into Koha. In the staff client I can see the bib records as well as the holdings information (call number - status - last seen - barcode). However, on the OPAC side, there is nothing. I search for known titles and authors, but there is nothing in the OPAC. I am not sure if there is still some problem with the items/holdings information in my 952s, or if there is a problem with my system settings. I tried adding a 952$a (location) to the records but this seemed to mess things up even more (couldn't see any holdings info on staff client side when I did this). So I don't have a location or "item type" in my holdings statement, and if these are needed, I cannot seem to get them in the right way. Also, don't know if this is related, but I still see "No_Library_Set" in the upper right hand corner of my staff client (even though I am logged in). I have pasted one of my MARC records, below. I welcome any advice you can offer to help me get my OPAC populated. Thanks!
