Check with your system administrator. We are working on a way to combine the images and provide an option for downloading the multipage images. Remember, however, that multiple pages mean larger files to download, not a problem with a high speed line, but a pain on slower links if you only want to look at a few pages. Licenses, or other documents with specific expiration dates, should not be sent directly to the electronic OPF, as they are not entered into the data tracking system at this time. OPFs may be viewed on any computer that has an appropriate viewing package.
Some information is available on the instruction page.
In reviewing my file I have found several errors. At the present time, this process could take several weeks. There are established guidelines for how documents are placed in the OPF that are used by folks doing the indexing. You just need to make sure that what kind of document you are providing is clearly identified. Based on that, the folks will put it in the correct place.
