Tell me how to create a manifest file.

A manifest file is a simple CSV file that contains two columns: ISBN-13 and Title Name. Find a sample here.

You can easily save a file as .CSV from Microsoft Excel, Google Spreadsheets, and other programs by choosing "File" and then "Save As." 

The file must be saved with the exact login name of your NetGalley account (like this: timberpress.csv). Remember, if you have multiple imprint accounts, you’ll need to create different manifests for each imprint account, to tell us where to put the titles. (Like this: tnfiction.csv; tnnonfiction.csv; tnkids.csv).

Here are some tips and tricks for creating a manifest file:

  • Please do not put any dashes or letters in the ISBN column; use only the 13 digits, like this: 9781234567890.
  • Excel has a strange default way of handling 13-digit numbers in columns, by converting the 13-digit number to a format like this: 9.78E+12. To correct this, click on the top of the Column "A" to select the entire column. Right click, and choose "Format Cells." In the "Number" tab, select "Number" and then "0" for the number of decimal places. Click OK.
  • You will have to do this each time you submit a manifest, or Excel will convert your ISBN to the 9.78E+12 format, and the manifest will not import.
