   Format: MarkdownItexRe-discovered this entry while checking what the $n$Lab has on Hovey's old idea that model categories should themselves form a "2-model category". I believe this idea long predates the first reference that was given here, but checking now I only find "Hovey's Algebraic Topology Problem List" in undated HTML form and migrated, apparently, to new servers. So I don't know if the original idea can still be cited properly, but I have added a brief note * [here](https://ncatlab.org/nlab/show/model+2-category#References) with what I did find. <a href="https://ncatlab.org/nlab/revision/diff/model+2-category/9">diff</a>, <a href="https://ncatlab.org/nlab/revision/model+2-category/9">v9</a>, <a href="https://ncatlab.org/nlab/show/model+2-category">current</a>
