Beckett used to grade / encapsulate notebooks (see first photo). However, when I tried to submit a few more notebooks a couple of years ago, they said that they no longer graded them and returned them to me unholdered. It's possible that they might have changed their policy, and you can try them.

CGC comics (not CGC cards but the same parent company) does grade / encapsulate notebooks (see second photo). However, they do not include the date on the flip unless the date is specifically officially stated somewhere on the notebook. Having someone who used the notebook originally scribble dates in the lined pages inside the notebook does not count. It has to be dates specifically officially printed by the manufacturer on the notebooks. Therefore, if you sent your notebook cover to CGC, like my example, they would not date it for you like Beckett did. I still preferred to holder my notebooks because some of them are very fragile with the pages practically ready to fall off, so I felt this would be a better way to preserve them. Also note that for CGC, I submitted these under the "Magazines" category for cgccomics. In general, I am very happy how they came out although of course, I wish they dated the notebooks with something like c1920s, but that's life.

One other thing that may affect your decision is that for Beckett and CGC, the holders are very thick, like around 1" or so. Therefore, if all you're encapsulating is a notebook cover, it may not present very well. Since I had full notebooks with pages for the most part, it looks okay for me.

I have not tried to submit notebooks or notebook covers to PSA. I am skeptical that they would holder them, but I have never tried. The covers would fit into their largest jumbo holders.
