How could I import manually written references from word to endnote for changing their style?
You could look at this thread http://community.thomsonreuters.com/t5/EndNote-How-To/can-endnote-scan-an-old-80-page-word-document-and-import-the/m-p/2685#M857 and here https://blogs.library.ucsf.edu/inplainsight/2012/10/17/transferring-a-word-bibliography-to-endnote/
Endnote needs to import a very structured file, or to use Hubmed or cb2Bib to assist in the import. I still think it easier to import topics from a database.
Many thanks, Leanne!
