As reported in THIS post, the "upload" button is not always available when returning to a project.
- The user compiled 1500 books
- The user returned to each project to upload
- The "upload" button was not always available.
I scrolled through my personal books and found some with and some without the upload button. NOTE: I have not uploaded many personal books, so I view this as confirmation. It is hard to tell, however, when there doesn't appear to be a means of determining which personal books have been uploaded. documents.logos.com does not show them.
I am no longer sure that what I wrote is true. I ended up filtering a second computer for edition:u and found around 100 resources... My primary installation has around 200. After checking about 30 resources, it appears that the ones which were uploaded have the button greyed out (as I would anticipate), while the ones I have not have the button available. Part of my confusion was how LONG my secondary computer took to download the personal book (which should be fairly small... only text).
