A couple of days ago I rumbled about some 3GPP specs having become so large that they become almost unmanageable in their word version and creating a PDF document out of them takes ages. One reader left a comment that pretty much fixes the issue for me and I guess his info is of wider interest: ETSI provides PDF versions of the specification documents in short order after they have been published. The 3GPP specification web pages even contain a link to the corresponding ETSI pages. The only thing you need to do to get access to the ETSI version is to register once. A great tip, thanks very much!
To try it yourself, have a look here for example and click on the link on the right next to the version of the document you are interested in.
