A total overhaul is performed on the MCNP Reference Collection. The new webpage has a filterable set of categories that are assigned to each document to assist in navigation (with an “All” category that is similar in length to the old webpage). In addition, BibTeX-style citation details are now available for each document. Each document is also renamed to provide additional information in the filename itself.

Because of some of these changes, most old links to specific sections of (and documents within) the reference collection no longer work. All links throughout the MCNP website have been updated accordingly, but please be sure bookmarks are up to date.
