Abstract: A multislide holder and editor comprises a rectangular plate-like body having a plurality of rectangular slide-receiving pockets formed between two sets of parallel ribs disposed at right angles to one another. Upon insertion into its respective pocket each slide enters two spaced parallel open-ended side edge engaging channels, each channel comprising two spaced edge-engaging members. One of these edge engaging members comprises at least two longitudinally spaced portions with a gap between them, while the other cooperating member is disposed opposite this gap and is of not greater length than the gap, so that the entire body can be formed by a single molding operation with linearly-moving relatively simple mold parts.
