There have been reports in dozens of publications that the OED has decided never to produce another edition in book form, although the Dictionary's publisher itself, OUP, claims that no firm decision has yet been taken (see here). Apparently sales of dictionaries are falling (as are sales of other types of reference books) because people can get the information for free on the internet.
Online dictionaries, and especially the online version of the OED, are fantastic resources and very convenient when one is writing at the computer, or reading something online. However, they do have limitations, and I, for one, would never part with my collection of traditional dictionaries, which I refer to just as often as to the OED online.
For one thing, I do not spend every waking hour at the computer, and still enjoy reading books and other publications sitting in the armchair far away from my computer. An online dictionary is no use to me in that situation. It's far more convenient to have a hard copy within easy reach.
You cannot browse an online computerised dictionary as easily as you can a hard copy. Online versions are getting better in this regard and you can often click on another headword that catches your fancy when looking up a word. But with a hard copy you might just spot something interesting in a definition of another word on the same page, that might take you off into an enjoyable reverie. Or, you can flick idly through a paper dictionary and something is sure to grab your attention.
One of the traditional uses people have always made of a dictionary is to look up how to spell a word. Some online dictionaries are not at all helpful in this regard, although things are generally getting better. Sometimes you need to key in the correct spelling in the first place to find the word. The OED online usually isn't too bad at this -- it ignores hyphens and apostrophes, for instance, whereas a CD-Rom of the single-volume ODE I used to have (until I finally flung it across the room with great force!) would only show a word if you typed it in exactly correctly. I remember using the CD-Rom once to check whether the cricket ground Lord's had an apostrophe, but typing in Lords got me nowhere. Only after I had tried Lords' then Lord's, did I get my answer. Not a major hassle, perhaps, but trying lady's finger followed by lady's-finger, ladies' finger, ladies-finger or any other combination would soon get tedious.
Admittedly, traditional dictionaries aren't completely foolproof in this regard -- if you don't know that psychology begins with a P you'll never find it in a dictionary -- but you can browse the whole page more easily if you are unsure whether broccoli has one C or two, or whether professor has two Fs and one S or two Ss and one F.
More importantly, if I look up the word 'hats' in a traditional dictionary, I won't find it, but I will find 'hat' pretty easily. If I look up the word 'hats' in the OED, I get the message 'There are no results'. The Dictionary does lead me to the place where hats would be if it were a headword, but it's not the 'hat' entry -- it's after hater, but before hatful, for some reason. Similarly, keying in 'cats' takes me directly to the catmint page. That's because cats-mint is an alternative name for catmint. If I look up 'fusspot', the OED tells me that there is no such word. There is, and it is in the OED, but it appears as a synonym of fussbox at the 'fuss' entry and is written on the page like this: "Comb., as fuss-box, -budget, -pot, a person who fusses", so the software doesn't pick up the whole word.
Most of today's newspaper articles about the online OED mention the subscription price -- over £200 p.a. What they don't mention is that you don't need to spend any money to access the OED -- not if you live in the UK anyway, and possibly in other English-speaking countries. Just about every local council in the UK subscribes to the OED on behalf of its residents, and if you find your local library service website you'll probably find a section entitled Online reference resources, or something similar, which will lead you to the OED. You will usually need your library card number and a PIN. If you don't know what I'm talking about and you use your local library, ask a librarian about it.
