I am not aware of any rule regarding this, but I put my vote toward adding the spaces.  Without them, it makes the last word and first words look jammed together in the program.

I tend to believe that professional typesetter put a space around the slash when the alternatives are multiple words. But then I'm not a professional typesetter.

The most common use is to replace the hyphen to make clear a strong joint between words or phrases, such as "the Ernest Hemingway/William Faulkner generation". Yet very often it is used to represent the concept or, especially in instruction books.

The symbol also appears in the phrase and/or, a prose representation of the logical concept of disjunction.

The virgule is also used to indicate a line break when quoting multiple lines from a poem, play, or headline. In this case (and only in this case), a space is placed before and after the virgule. For example: "Love alters not with his brief hours and weeks, / But bears it out even to the edge of doom".

British English particularly makes use of this alternation with a hyphen in forming abbreviations. Many examples are found in writings during the Second World War. For example, 'S/E' means 'single-engined', as a quick way of writing a type of aircraft. And in the US, "O/O" is used by trucking firms or taxicabs to mean "owner-operator" (or "owned and operated by"). Notice that the phrase has a hyphen, whereas the abbreviation uses the slash.

The slash is often used, perhaps incorrectly, to separate the letters in a two-letter initialism such as R/C (short for radio control) or w/o (without). Purists strongly discourage this newer use of the symbol. However, since other uses of the slash with individual characters are highly context-specific, confusion is not likely to arise. Other examples include b/w (between or, sometimes, black and white), w/e (whatever, also weekend or week ending), and r/w (read-write).

Never include spaces on either side of a slash.

I agree!

There have been a few contributions of double features now where the contributor adds spaces on both sides of the "/" sign in the title, saying he adds spacing "as per the rules".

Example:

Village of the Damned/Children of the Damned

is corrected to

Village of the Damned / Children of the Damned

Just how trivial can discussions in these forums become? Either form clearly indicates what is happening here. Does it really matter which is used?

Unfortunately this is one of the more overlooked part of the rules, yet I find it one of the most important of them all, and it covers this perfectly:

"Make sure your contributions add significant value to the database."

Personally I would find a contribution adding or removing such spaces in violation of this rule, and simply vote no.

I'll do the same if someone for example are trying to change between the two "legal" ways of capitalizing Danish movie titles.

I consider the following changes to be significent:
1) Add missing information (no matter if I personally use it or not)
2) Changes of data that is wrong or in clearly in violation of the rules (so for the unclear rules, I'll vote no to changes from one interpretation to another).

Anything else - expect a no from me.

I like it better without spaces.

The majority of titles in my collection have no spaces, and this is how I understand it should be.
