We have a sections of A's, B's, C's, D's, E-F's, etc in the Feature area and sections of A-D, E-L, etc in the Children's section with the Performance not alphabetized at all (this is our smallest section). The A section has all the Feature Films whose title begins with A, ignoring the a, an, or the as the first word. We do not alphabetize after the first letter - we found we could not keep them in order without a lot of shelver time which we do not have. Even on the section of shelves with two letters, the E-F section for example, we do not do any more arranging. The video "Field of Dreams" could be on the top shelf, the middle shelf, or the bottom shelf. Its location was determined by where there was room in this section of shelving when the video was returned and shelved.
We mark the spine of most of the video cases with a genre label - comedy, mystery, western, foreign, war, classic, horror, musical, sci fic, etc. If we can not clearly identify it as one of these genre we do not give it a sticker.
We have most of our video's in the black cases with a brief plot summary included inside the case. We recently switched to the clear plastic squeeze-bottom cases so that we can keep the cardboard case with its description and save some processing time.
It is sometimes difficult to locate a video since you may have 3 or 4 shelves of A's to look through but this is how we have had the videos from the start of our collection and our patrons are used to it.
Hope this helps.
