Hmmm, I'm assuming you're the GM? This comes to a question of what flavor of campaign you're looking for. Is magic commonplace? If so, you go to the store, and you buy a scroll of Melf's Acid Arrow, and people generally know what that looks like, and there's nothing special about the common spell scroll that isn't also special about your average enchanted sword. But if magic is rare? Or if certain spells are super-rare? Your best bet is probably a Handout, as found on the character sheets tab. I'm assuming you'd do this because you want something to look special, so best bet is: go online, find a picture of a piece of parchment, maybe yellowed, or water spotted, or whatnot. Paste that into powerpoint, or your editor of choice. Go to a font website you like, and find a neat looking elf/dwarf/dragon font. Write down the spell, and what it does, in a text block on top of the image. Save that, paste it into the images part of a handout, call it 'mysterious parchment' or whatnot. Then, let all players see it in the 'who can view' block up top. Second, change the font in the original to Arial, or Helvetica, or something else readable, and make a second handout, then only give access to those who should know/learn how to read it.
