electronic-deposit eligibility
Some published works remain subject to best-edition or physical-deposit requirements even when the application and payment are submitted through eCO.
How we handle it: Use this preset only when the eCO application permits an electronic literary-work deposit; otherwise follow the generated shipping-slip instructions.
supported format subset
eCO accepts many image, text, presentation and compressed formats in addition to PDF. UploadPrep prepares the official PDF subset for literary works.
How we handle it: Convert an eligible electronic literary work to PDF before using UploadPrep, or upload another accepted type directly in eCO.
