An object that takes physical, material, or corporeal form can be held and seen by humans. When we describe the opposite, something that cannot be held or seen by the naked eye, words like spiritual or non-material are used. I'm looking for a word that's more specific: something to describe the sequences of numbers packed into data chips and technology whatsits.
"Information, whether of material or ________ form, can be found at the library."
Assume that the library carries books and CDs/DVDs. In order to avoid wordy descriptions, does anyone have any suggestions for a single word that can fill the blank? I avoided antonyms of "physical" because they refer to things that are otherworldly.
