Since local collections are handled at a collection level, it is not possible to manually add an item. In order to correct these holdings, you need to contact NHS_Support@wolterskluwer.com with the details of the local full-text collection and the print collection you would like them adding to.
Please send a single file (no need to separate full text and print) in KBART format to NHS Support. You can request also this KBART format file from NHS_Support@wolterskluwer.com. You can then modify/change as needed, return it back to Wolters Kluwer and they will upload the new modified file.
