The post-print (also called 'Author Accepted Manuscript, 'AAM' or 'AM') is the version of the article that has been peer reviewed and accepted for publication, but before layout and type-setting by the publisher.
'Proofs' and 'offprints' are not post-prints and may not be deposited in CURIS or other repositories.
Guide on how to obtain post-prints
The pre-print (also called 'Work in Progress' or 'Submitted Version') is the version of the article submitted to the journal but before it has been peer reviewed and finally accepted for publication.
Publisher’s version (also called 'Version of Record' or 'VoR') is the final published version of the article. It is formatted with the publisher's layout and volume and issue number. Unless the article is published as Open Access in a golden or hybrid journal (subscription journals that offer Open Access after payment of a publishing fee), the publisher’s version may not generally be made Open Access.
When journals share post-prints with the authors, it sometimes happens that figures etc. are sent in separate files, e.g. in separate Word or pdf files. If you as author want figures and illustrations to be included in the text document itself, you must do this yourself before the post-print is sent to the library. You can also merge the files into one pdf. Here you can use the free online service Smallpdf.
