Bibliography mixup after melting two documents together
I copy & pasted two documents together. After generating the bibliography it doesn't melt the authors right together. Like I had at the first file quoted two documents of the same author in the same year (author 200xa, author 200xb). Pasting it in the second file with a third source from the same year already doesn't make it go author 200xa, 200xb and 200xc but just keeps it without a letter. Any suggestions how to fix this?
I can nail it now more down: It is NOT working with the Harvard Style, but it IS working with the Chicago style.
Very very strange...
