This feature allows you to convert existing collections of PDF files into EndNote references with minimal typing and copying by extracting Digital Object identifiers (DOI) from PDF files. The system matches DOI information with data available from CrossRef (www.CrossRef.org) by capturing bibliographic content and creating new EndNote references.
To import a PDF file:
Open the library into which you want to import the references.
From the File menu, select Import > File to open the Import File dialog.
Click the Choose button Use the top half of the dialog to locate and open the file you want to import from your hard drive.
Select the needed PDF file, and then click OpenImport.
Select PDF from the Import Option list.
Select an option from the Duplicates list:
Import All: Imports all references, including duplicates.
Discard Duplicates: Imports all references except duplicates.
Import into Duplicates Library: Duplicate references are imported into a library called File-Dupl.enl, where ”File" is the name of the library into which you are importing.
By default, a reference is considered a duplicate when the Author, Year, Title, and Reference Type match a reference already in the library. See Duplicate Preferences if you would like to change the duplicates criteria.
Select a Text Translation option. The default value is No Translation.
This option allows you to specify the text character encoding of the file you import, so that extended characters transfer correctly. You should verify the setting with your database provider. Some U.S. databases that contain extended characters require ANSI-Latin1 or UTF8. MARC format files may require ANSEL translation. You might be able to use No Translation for text files that do not contain any extended characters.
Click Import to import the file to your library.
Note: See Importing PDF Folders to Create New Records for instructions on how to import multiple PDF files stored within a single folder.
Note: When performing the import function, if there are two DOIs found in the first two pages of a PDF document, EndNote will put at least one DOI in the DOI field for data extraction. The PDF is then attached and the file name is put in the Title field.
When the import is complete, the new record is stored in the Imported References group, and will include bibliographic information given for the Digital Object Identifier (DOI) mined from the PDF file such as title, author, volume, issue, page, year, and DOI. This is a perfect time to add a keyword to the imported reference with the Change Field command, or to peruse the imported data to make sure it imported as expected. Make sure to check references that contain extended characters.
The Imported References group is a temporary group that is replaced each time you import another set of references. It is removed when you exit EndNote (although the references remain in the library).
To return all of your references to the library display (including the newly imported ones), select how All References from the References menu or click the All References group.
