• Marker texts are accurate and provide historical context,
• Markers are installed at appropriate sites, and
• Necessary permissions have been obtained

• IHB staff will carefully review every application submitted; the number and quality of 2026 applications submitted will be a factor in determining the number of applications approved to move forward.
• IHB staff performs much of the final research and editing required for the marker; however, the applicant must provide reliable, locally-available primary source materials for each point on a marker. A successful marker application involves collaboration between IHB and marker applicants.

Topic Considerations for 2026-2027 Markers:

• IHB encourages applications for topics that will celebrate notable anniversaries in 2027. For instance, topics that are celebrating semi-centennials (1977), 75 year anniversaries (1952), centennials (1927), sesquicentennials (1877), 175 year anniversaries (1852), bicentennials (1827), etc. are particularly welcome. Topics related to the nation's semiquincentennial (250th anniversary) are still eligible, however please note that markers for approved applications would not be ready until 2027.
• IHB guidelines stipulate that no individual may be the topic of a marker until twenty years after his or her death. Thus, notable Hoosiers who died in 2007 or earlier can be application candidates for markers placed in 2027. It is at the discretion of the Indiana Library and Historical Board, upon the recommendation of IHB, to make any exceptions to this guideline.
• IHB encourages topics that help fill geographical or subject gaps in the historical marker collection.
