Dear Jim,

My apologies for the delay replying to your message.

As I announced recently in a separate message
&P=67394) I am very pleased to inform participants of this forum that the
CPS is now fully compliant with the Open Archives Initiative protocol.
Registration details may be viewed at

Thank you for your other questions and comments. I have responded to these

In the previous message you wrote:

The author may add more supplementary files or revise the full text of the
preprint at any time during the research process. These options are indeed
not mutually exclusive. However, once access to the final version has been
redirected, authors are no longer able to revise the full-text of the
article further, or add more supplementary files.

Yes, the original version and all supplementary files remain
fully-accessible after access to the final version has been redirected. Some
authors have also uploaded versions of the full-text article into the
supplementary files section. This could include, for example, an HTML
version of the full-text which is created in PDF format as standard.

I have looked through the preprints posted to date and 11 of the 333
articles have had the access redirected. It is more difficult to judge how
many more have gone on to be published. However, I have seen a number of
author comments such as "This paper has been submitted to..." and "This
paper has now been published in... and you may also access the published
version at...". It would certainly be very interesting to investigate this

I hope that these comments have helped to answer your questions. I would of
course welcome more questions, comments or opinions on the Chemistry
Preprint Server from any participant of this forum.

Best regards,
