Adobe used to publish and distribute the pdf spec on their developers site. Used to be able to read it and hand code PDFs. Not sure if such a resource is still available.

Wish I still had a copy but it was a while back.

The spec is still available freely: http://www.adobe.com/devnet/pdf/pdf_reference.html

For historical interest, older versions (going back to 1.3) are here: http://www.adobe.com/devnet/pdf/pdf_reference_archive.html

1.2, 1.1, and 1.0 can be found elsewhere on the Internet.

Sweet, thanks. Haven't been on the Adobe devnet in a while
