Now, having mapped out a few different key points to search for in the databases, I will create a bibliography of secondary sources to compile the 10-15 most relevant academic texts on the history and sanctity of the l’Église de Sainte-Croix. Because I am focusing on what may have attracted pilgrims to this site in the 12th century, when the Liber Sancti Iacobi was published, I have tried to keep my sources as relevant to this time period and before, rather than including sources that deal with the latter portion of the history of the Cathedral of Sainte-Croix.
(This is to say, I sifted through many, many pages full of sources concerning Joan of Arc in order to find what I present here.)

Concluding Thoughts and Next Steps
I have located several useful texts here which provide both historical context for the broader understanding of what drew pilgrims and patrons to l’Église de Sainte-Croix. However, I had more difficulty than I expected locating them. I believe I will need to experiment with even more key phrases (having exhausted all forms of Saint Euverte, Cathedral d’Orléans, the True Cross, etc.), perhaps in more languages. There is (understandably) a lot of scholarship on the topic in modern European languages, several of which I included above. However, I have a feeling that there is more information available online that I have yet to locate. Perhaps digging into these texts and their citations will guide me to more sources. I will also play around with the language in which I am conducting my searches to include more of these European scholars.
