Special note: Documents appearing in the TAPPI online version of the Standards and TIPs are updated once a month (usually around the 30th). So it is possible that there is a delay between the publication announcement and the posting online. If you are a subscriber to the online access to Standards and TIPs and you are in a hurry for new documents that have not yet been posted, you can send a request for TIPs to tip@tappi.org or for Standards to standards@tappi.org.
