What is it?

The endnote export format is a format used to save human-readable data from EndNote, a program for personal reference management.

How do I get data in this format?

Most endnote export files obviously originate from EndNote software, but some online sources may support it as well. Additionally, the EndNote export format is an adaptation of an older format known as 'Refer'. Network Workbench should also support these files, as long as they are renamed to have the ".enw" extension.

This documentation refers to Endnote 10, so the specific steps may differ slightly for previous or later versions. The basic idea is to make Endnote export the library in the "Endnote Export" format, and make sure the resulting text file has the extension ".enw".

To export an EndNote library to the correct format, the process is as follows...

  1. Load whatever bibliography library you want in Endnote.
  2. Inspect the drop-down box near the top of the Endnote window. If it contains the entry "Endnote Export", skip to step 5. If not, continue on to step 3.
  3. Go to Edit -> Output Styles -> Open Style Manager.
  4. Find the "Endnote Export" style in the list, select the checkbox, and close the Style Manager window.
  5. Select "EndNote Export" as your export style in the drop-down box near the top of the EndNote screen.
  6. Go to File -> Export
  7. Save as type "Text File (*.txt)", and save the file with whatever name you like.
  8. For use in NWB, rename the file to have the extension ".enw", instead of the default ".txt" extension. Note that on windows, file extensions are hidden by default, so you may need to open and resave the file in notepad instead of renaming it on the desktop. When saving from Notepad, make sure to select Save as type "All Files", to prevent Notepad from automatically adding the ".txt" extension.
How is it used in Network Workbench?

NWB can extract co-authorship and co-citation information from .enw files. using the Extract Co-Occurrence Network from Table Algorithm, if the required author and citation information is present. Burst Detection can also be performed on its contents.

What should I know about how NWB handles this format?

NWB does not perform any special cleaning or processing on the data. It simply converts the data into a table, from which networks can be extracted using the "Extract Co-Occurrence Network from Table" algorithm, which can be found under Preprocessing. Authors are already delimited using the "|" character.

What should I know about the format itself?

ENW files contain a list of records, each separated by two or more lines. Records in ENW consist of a list of single-character tags, followed by a space, and then the contents of that tag. Each tag has a special meaning in ENW, for instance A means Author, and T means title. (There is some discrepancy between ENW and the original refer format when it comes to the meaning of more obscure tags).
