Included in the records from Lodge #225 are records from other lodges that either were absorbed into this one or were dissolved as the mining camps closed and as individuals did not keep up memberships. Also included are some records from two Slovene Progressive Benefit Society (Slovenska Suobodomiselna Podporna Zuesza, or SSPZ) lodges that were located in Kansas, #14 Yale and #66 Yale. These two groups merged with #9 Yale SNPJ Lodge, which in 1995 was transferred to Camp 50 #225 Lodge. Types of records from these groups consist of minute books and charters, treasurers' reports, membership lists, benefit listings, secretary's books, and other such materials. Also in the collection is a centenary anniversary book for the national organization, from 2004. The records date from throughout the 20th century, and the early records are often written in Slovenian.
