unlinked all references
Instead of syncing, i read somewhere that i could copy the zotero library files, put them on a usb stick and take that to a different computer. There i deleted the earlier version of the library and pasted the one i had on the usb. This, i suspect, i effectively unlinked all of my references. I noticed when i went into the library and tidied many URL's, but when i refreshed it didnt change the bibliography. However it does change when i reinsert the citation using the library. So, i need to do this throughout the doc, correct?
