Modelar Extra is the expanded edition of the Czech magazine Modelar. It appears outside the regular monthly sequence, carries its own numbering and runs to a greater length than a standard issue, which is why it is kept separately here. Each edition is identified by its own number and year of publication; what it contains is described on that edition.
Because the specials are not tied to monthly periodicity, they do not fit the volume-by-year structure and are easily overlooked inside the main run - keeping them apart helps anyone who collects only these. The regular monthly numbers are split by year in the main Modelar magazine section, and editions without a stated volume year in older Modelar issues. Kits for what you read about sit in plastic model kits.
