How do I open libraries created with EndNote 8/9/X/X3/X4 in older versions of EndNote?
Libraries created in Endnote 8, 9, X, X3 or X4 are not backwards-compatible with previous versions. To use EndNote 8/9/X/X3/X4 libraries with an older version of EndNote you will need to import the library from EndNote 8/9/X/X3/X4 into the older version of the program: • Open the library in EndNote 8/9/X/X3/X4 and make sure all references are showing. • Select Refer Export as the output style. • Go to File > Export…, enter a file name, and save the file to a convenient location such as the Desktop. • Next, in the older version of EndNote, create a new library or open an existing one. • Go to File > Import. • Click the Choose File button and select the text file you just created. • Under Import Option select Refer/BibX. • Click the Import button.
