In your transcription convert the old Latin letters into modern letters (see the LC-PCC-PS 1.4) Latin contains some letters that look different to our modern letters, for example a Latin S looks more like an F, or a Latin U looks like a V. When transcribing, keep in mind the intent of the letter; an S is still an S even if it looks more like a modern F. We are still adhering to transcribing the title on the item, its just certain letters look different on modern keyboards. With this in mind there is no need to make an added entry.
